I have the following jquery plugin on my client side which gives me a on/off switch. I need "off" and "on" to trigger different server side scripts. I know how this can be achieved with a regular "on-click" button, but not with a switch button.
Here is what's in client-side:
<div id="second_div">
<form>
<div style="float: left; width: 50%;">
<p style="padding-bottom: 13px;"><em>Checkbox</em></p>
<p><input type="checkbox" name="check-1" value="4" class="lcs_check" autocomplete="off" /></p>
</div>
</form>
<div style=" clear: both;"></div>
</div>
<div id="third_div">
<em style="color: #777; font-size: 14px;">Check your browser console to see triggered events</em>
</div>
<p></p>
I would like "off" to trigger one function "google.script.run.loggOff();
I would like "on" to trigger another function "google.script.run.loggOn();
This is usually how i do it with an 'onclick button':
Client Side (on-click button):
<button type="button" onclick="google.script.run.createDoc();">Create Google Doc</button>
<script>
google.script.run.createDoc();
</script>
Server Side (on-click button):
function createDoc() {
var copyDoc = DocumentApp.openById(copyId);
copyDoc.saveAndClose();
}
Maybe I'm misunderstanding the question, but if you want to add click functions the on and off you can do something like this.
//off
$('.lcs_check').click(function() {
$('.lcs_check').attr('id','loggOff');
google.script.run.loggOff();
});
//on
$('.lcs_check #loggOff').click(function() {
$('.lcs_check #loggOff').removeAttr('id','loggOff');
google.script.run.loggOn();
});
This plugin is LC-switch, i found the github page and a more detailled demo page.
In the demo page there is a Event section, there is 3 events for what you trying to accomplish.
// triggered each time a field changes status
$('body').delegate('.lcs_check', 'lcs-statuschange', function() {
var status = ($(this).is(':checked')) ? 'checked' : 'unchecked';
console.log('field changed status: '+ status );
});
// triggered each time a field is checked
$('body').delegate('.lcs_check', 'lcs-on', function() {
console.log('field is checked');
});
// triggered each time a field is unchecked
$('body').delegate('.lcs_check', 'lcs-off', function() {
console.log('field is unchecked');
});
But it look like each of this event are called after state has changed. I didn't find a way to have click information before state is changed.
I have a text field which should hide when it loses focus. I also have a button. The problem is, when you click the button, the text field first loses focus, which moves the button, preventing it from receiving the click event.
HTML:
<div>
<p> Focus on the text field, and then click the button </p>
<div id="hideMeOnFocusOut">
<input type="text" id="focusMeOut" autofocus>
<br><br><br>
</div>
<button id="clickMe">click me</button>
</div>
JS:
$(function() {
$('#focusMeOut').on('focusout', function(e) {
$('#hideMeOnFocusOut').hide();
});
$('#clickMe').on('click', function(e) {
alert('clicked!');
});
});
http://jsfiddle.net/u86ycf5e/
The button should still move. But it should also receive the click event.
Add a container with a height around the element you are hiding: Fiddle
.container {
height: 50px;
}
HTML
<div class="container">
<div id="hideMeOnFocusOut">
<input type="text" id="focusMeOut" autofocus>
<br>
<br>
<br>
</div>
</div>
Alternatively, you could make the element hide after a short delay via setTimeout like so:
$('#focusMeOut').on('focusout', function (e) {
setTimeout(function() {
$('#hideMeOnFocusOut').hide();
}, 250);
});
Other fiddle
Try ...
$('#focusMeOut').on('focusout', function(e) {
$('#hideMeOnFocusOut').hide();
if (e.relatedTarget.id==="clickMe") {
$("#clickMe").trigger('click');
}
});
This will check to see if the button was clicked and fire it ...
Hide the text box instead with:
$('#focusMeOut').on('focusout', function(e) {
$(this).hide(); //this line changed
});
and optionally set the height of the <div> to prevent button moving with this CSS:
#hideMeOnFocusOut {
height:80px;
}
You might want to rename your IDs more appropriately now.

What I'm trying to do here is to show a loading box that follows cursor after submitting a form using MooTools. However, I've simplified the problem into just 1 div and 1 form.
script:
document.addEvent('domready', function(){
$('test_form').addEvent('submit', function(){
var box = $('box');
document.addEvent('mousemove', function(e){
box.setStyles({
top: e.page.y,
left: e.page.x
});
});
box.setStyle('display', 'block');
return false;
});
});
html:
<div id="box">
</div>
<form id="test_form" action="">
<label>Name: </label><input type="text" name="name" /><br/>
<input type="submit" value="Submit" />
</form>
css:
#box {
width: 50px;
height: 50px;
background-color: blue;
position: absolute;
display: none;
}
#test_form {
margin-left: 150px;
}
When the form is submitted, it will show the hidden blue div and it will follow the cursor. However, I can't make the div appear at mouse position when the form is submitted. The 'mousemove' will not fire until we move the mouse; thus, the blue div appears at position (0,0) immediately after showing. Is there a way to get the mouse position right after the form is submitted? Or is there an alternative way to do it?
Any suggestions is greatly appreciated!
Updated:
I don't want to add mouse event (mousemove) before the form is submitted. The reason is simply because I don't want the javascript to keep on checking the mouse position when it's not necessary. Just try to avoid performance issue!
basically, the submit is an event but its event.type is submit and it won't contain mouse info.
your bet is to re-arrange your javascript so it moves the box quietly all the time and just shows the box by changing display when submitted. something like that:
http://jsfiddle.net/jtLwj/
(function() {
var box = $('box');
document.addEvent('mousemove', function(e) {
box.setStyles({
top: e.page.y,
left: e.page.x
});
});
$('test_form').addEvent('submit', function(ev) {
ev.stop();
box.setStyle('display', 'block');
var sizes = box.getPosition();
box.set("html", [sizes.x, ' x ', sizes.y].join("<br/>"));
});
})();
reading the box position after submit will return your cursor :)
downside: latency of changing css for the invis box before submit.
edit better version w/o the change to dom all the time:
(function() {
var lastEventObject, eventListener = function(e) {
// keep a scoped referene of the last known mouse event object
lastEventObject = e;
};
document.addEvent('mousemove', eventListener);
document.id('test_form').addEvent('submit', function(e) {
e.stop();
// not needed anymore...
document.removeEvent("mousemove", eventListener);
// show the box at last known mouse loc
document.id("box").setStyles({
display: 'block',
left: lastEventObject.page.x,
top: lastEventObject.page.y
});
// attach to mousemove or whatever....
});
})();
this is as good as it will get, I'm afraid. the footprint of the reference to the event object is minimal at best.

I'd like to make a click event fire on an <input type="file"> tag programmatically.
Just calling click() doesn't seem to do anything or at least it doesn't pop up a file selection dialog.
I've been experimenting with capturing events using listeners and redirecting the event, but I haven't been able to get that to actually perform the event like someone clicked on it.
I have been searching for solution to this whole day. And these are the conclusions that I have made:
For the security reasons Opera and Firefox don't allow to trigger file input.
The only convenient alternative is to create a "hidden" file input (using opacity, not "hidden" or "display: none"!) and afterwards create the button "below" it. In this way the button is seen but on user click it actually activates the file input.
Upload File
You cannot do that in all browsers, supposedly IE does allow it, but Mozilla and Opera do not.
When you compose a message in GMail, the 'attach files' feature is implemented one way for IE and any browser that supports this, and then implemented another way for Firefox and those browsers that do not.
I don't know why you cannot do it, but one thing that is a security risk, and which you are not allowed to do in any browser, is programmatically set the file name on the HTML File element.
You can fire click() on any browser but some browsers need the element to be visible and focused. Here's a jQuery example:
$('#input_element').show();
$('#input_element').focus();
$('#input_element').click();
$('#input_element').hide();
It works with the hide before the click() but I don't know if it works without calling the show method. Never tried this on Opera, I tested on IE/FF/Safari/Chrome and it works. I hope this will help.
THIS IS POSSIBLE:
Under FF4+, Opera ?, Chrome:
but:
inputElement.click() should be called from user action context! (not script execution context)
<input type="file" /> should be visible (inputElement.style.display !== 'none') (you can hide it with visibility or something other, but not "display" property)
just use a label tag, that way you can hide the input, and make it work through its related label
https://developer.mozilla.org/fr/docs/Web/HTML/Element/Label
For those who understand that you have to overlay an invisible form over the link, but are too lazy to write, I wrote it for you. Well, for me, but might as well share. Comments are welcome.
HTML (Somewhere):
<a id="fileLink" href="javascript:fileBrowse();" onmouseover="fileMove();">File Browse</a>
HTML (Somewhere you don't care about):
<div id="uploadForm" style="filter:alpha(opacity=0); opacity: 0.0; width: 300px; cursor: pointer;">
<form method="POST" enctype="multipart/form-data">
<input type="file" name="file" />
</form>
</div>
JavaScript:
function pageY(el) {
var ot = 0;
while (el && el.offsetParent != el) {
ot += el.offsetTop ? el.offsetTop : 0;
el = el.offsetParent;
}
return ot;
}
function pageX(el) {
var ol = 0;
while (el && el.offsetParent != el) {
ol += el.offsetLeft ? el.offsetLeft : 0;
el = el.offsetParent;
}
return ol;
}
function fileMove() {
if (navigator.appName == "Microsoft Internet Explorer") {
return; // Don't need to do this in IE.
}
var link = document.getElementById("fileLink");
var form = document.getElementById("uploadForm");
var x = pageX(link);
var y = pageY(link);
form.style.position = 'absolute';
form.style.left = x + 'px';
form.style.top = y + 'px';
}
function fileBrowse() {
// This works in IE only. Doesn't do jack in FF. :(
var browseField = document.getElementById("uploadForm").file;
browseField.click();
}
Try this solution: http://code.google.com/p/upload-at-click/
If you want the click method to work on Chrome, Firefox, etc, apply the following style to your input file. It will be perfectly hidden, it's like you do a display: none;
#fileInput {
visibility: hidden;
position: absolute;
top: 0;
left: -5000px;
}
It's that simple, I tested it works!
$(document).one('mousemove', function() { $(element).trigger('click') } );
Worked for me when I ran into similar problem, it's a regular eRube Goldberg.
WORKING SOLUTION
Let me add to this old post, a working solution I used to use that works in probably 80% or more of all browsers both new and old.
The solution is complex yet simple. The first step is to make use of CSS and guise the input file type with "under-elements" that show through as it has an opacity of 0. The next step is to use JavaScript to update its label as needed.
HTML The ID's are simply inserted if you wanted a quick way to access a specific element, the classes however, are a must as they relate to the CSS that sets this whole process up
<div class="file-input wrapper">
<input id="inpFile0" type="file" class="file-input control" />
<div class="file-input content">
<label id="inpFileOutput0" for="inpFileButton" class="file-input output">Click Here</label>
<input id="inpFileButton0" type="button" class="file-input button" value="Select File" />
</div>
</div>
CSS Keep in mind, coloring and font-styles and such are totally your preference, if you use this basic CSS, you can always use after-end mark up to style as you please, this is shown in the jsFiddle listed at the end.
.file-test-area {
border: 1px solid;
margin: .5em;
padding: 1em;
}
.file-input {
cursor: pointer !important;
}
.file-input * {
cursor: pointer !important;
display: inline-block;
}
.file-input.wrapper {
display: inline-block;
font-size: 14px;
height: auto;
overflow: hidden;
position: relative;
width: auto;
}
.file-input.control {
-moz-opacity:0 ;
filter:alpha(opacity: 0);
opacity: 0;
height: 100%;
position: absolute;
text-align: right;
width: 100%;
z-index: 2;
}
.file-input.content {
position: relative;
top: 0px;
left: 0px;
z-index: 1;
}
.file-input.output {
background-color: #FFC;
font-size: .8em;
padding: .2em .2em .2em .4em;
text-align: center;
width: 10em;
}
.file-input.button {
border: none;
font-weight: bold;
margin-left: .25em;
padding: 0 .25em;
}
JavaScript Pure and true, however, some OLDER (retired) browsers may still have trouble with it (like Netscrape 2!)
var inp = document.getElementsByTagName('input');
for (var i=0;i<inp.length;i++) {
if (inp[i].type != 'file') continue;
inp[i].relatedElement = inp[i].parentNode.getElementsByTagName('label')[0];
inp[i].onchange /*= inp[i].onmouseout*/ = function () {
this.relatedElement.innerHTML = this.value;
};
};
Working jsFiddle Example
It works :
For security reasons on Firefox and Opera, you can't fire the click on file input, but you can simulate with MouseEvents :
<script>
click=function(element){
if(element!=null){
try {element.click();}
catch(e) {
var evt = document.createEvent("MouseEvents");
evt.initMouseEvent("click",true,true,window,0,0,0,0,0,false,false,false,false,0,null);
element.dispatchEvent(evt);
}
}
};
</script>
<input type="button" value="upload" onclick="click(document.getElementById('inputFile'));"><input type="file" id="inputFile" style="display:none">
I know this is old, and all these solutions are hacks around browser security precautions with real value.
That said, as of today, fileInput.click() works in current Chrome (36.0.1985.125 m) and current Firefox ESR (24.7.0), but not in current IE (11.0.9600.17207). Overlaying a file field with opacity 0 on top of a button works, but I wanted a link element as the visible trigger, and hover underlining doesn't quite work in any browser. It flashes on then disappears, probably the browser thinking through whether hover styling actually applies or not.
But I did find a solution that works in all those browsers. I won't claim to have tested every version of every browser, or that I know it'll continue to work forever, but it appears to meet my needs now.
It's simple: Position the file input field offscreen (position: absolute; top: -5000px), put a label element around it, and trigger the click on the label, instead of the file field itself.
Note that the link does need to be scripted to call the click method of the label, it doesn't do that automatically, like when you click on text inside a label element. Apparently the link element captures the click, and it doesn't make it through to the label.
Note also that this doesn't provide a way to show the currently selected file, since the field is offscreen. I wanted to submit immediately when a file was selected, so that's not a problem for me, but you'll need a somewhat different approach if your situation is different.
JS Fiddle: http://jsfiddle.net/eyedean/1bw357kw/
popFileSelector = function() {
var el = document.getElementById("fileElem");
if (el) {
el.click();
}
};
window.popRightAway = function() {
document.getElementById('log').innerHTML += 'I am right away!<br />';
popFileSelector();
};
window.popWithDelay = function() {
document.getElementById('log').innerHTML += 'I am gonna delay!<br />';
window.setTimeout(function() {
document.getElementById('log').innerHTML += 'I was delayed!<br />';
popFileSelector();
}, 1000);
};
<body>
<form>
<input type="file" id="fileElem" multiple accept="image/*" style="display:none" onchange="handleFiles(this.files)" />
</form>
<a onclick="popRightAway()" href="#">Pop Now</a>
<br />
<a onclick="popWithDelay()" href="#">Pop With 1 Second Delay</a>
<div id="log">Log: <br /></div>
</body>
Here is pure JavaScript solution to this problem. Works well across all browsers
<script>
function upload_image_init(){
var elem = document.getElementById('file');
if(elem && document.createEvent) {
var evt = document.createEvent("MouseEvents");
evt.initEvent("click", true, false);
elem.dispatchEvent(evt);
}
}
</script>
This code works for me. Is this what you are trying to do?
<input type="file" style="position:absolute;left:-999px;" id="fileinput" />
<button id="addfiles" >Add files</button>
<script language="javascript" type="text/javascript">
$("#addfiles").click(function(){
$("#fileinput").click();
});
</script>
My solution for Safari with jQuery and jQuery-ui:
$("<input type='file' class='ui-helper-hidden-accessible' />").appendTo("body").focus().trigger('click');
There are ways to redirect events to the control but don't expect to be able to easily fire events to the fire control yourself as the browsers will try to block that for (good) security reasons.
If you only need the file dialog to show up when a user clicks something, let's say because you want better looking file upload buttons, then you might want to take a look at what Shaun Inman came up with.
I've been able to achieve keyboard triggering with creative shifting of focus in and out of the control between keydown, keypress & keyup events. YMMV.
My sincere advice is to leave this the alone, because this is a world of browser-incompatibility-pain. Minor browser updates may also block tricks without warning and you may have to keep reinventing hacks to keep it working.
I was researching this a while ago because I wanted to create a custom button that would open the file dialog and start the upload immediately. I just noticed something that might make this possible - firefox seems to open the dialog when you click anywhere on the upload. So the following might do it:
Create a file upload and a separate element containing an image that you want to use as the button
Arrange them to overlap and make the file element backgroud and border transparent so the button is the only thing visible
Add the javascript to make IE open the dialog when the button/file input is clicked
Use an onchange event to submit the form when a file is selected
This is only theoretical since I already used another method to solve the problem but it just might work.
I had a <input type="button"> tag hidden from view. What I did was attaching the "onClick" event to any visible component of any type such as a label. This was done using either Google Chrome's Developer Tools or Mozilla Firefox's Firebug using the right-click "edit HTML" command. In this event specify the following script or something similar:
If you have JQuery:
$('#id_of_component').click();
if not:
document.getElementById('id_of_component').click();
Thanks.
Hey this solution works.
for download we should be using MSBLOB
$scope.getSingleInvoicePDF = function(invoiceNumberEntity) {
var fileName = invoiceNumberEntity + ".pdf";
var pdfDownload = document.createElement("a");
document.body.appendChild(pdfDownload);
AngularWebService.getFileWithSuffix("ezbillpdfget",invoiceNumberEntity,"pdf" ).then(function(returnedJSON) {
var fileBlob = new Blob([returnedJSON.data], {type: 'application/pdf'});
if (navigator.appVersion.toString().indexOf('.NET') > 0) { // for IE browser
window.navigator.msSaveBlob(fileBlob, fileName);
} else { // for other browsers
var fileURL = window.URL.createObjectURL(fileBlob);
pdfDownload.href = fileURL;
pdfDownload.download = fileName;
pdfDownload.click();
}
});
};
For AngularJS or even for normal javascript.
This will now be possible in Firefox 4, with the caveat that it counts as a pop-up window and will therefore be blocked whenever a pop-up window would have been.
Here is solution that work for me:
CSS:
#uploadtruefield {
left: 225px;
opacity: 0;
position: absolute;
right: 0;
top: 266px;
opacity:0;
-moz-opacity:0;
filter:alpha(opacity:0);
width: 270px;
z-index: 2;
}
.uploadmask {
background:url(../img/browse.gif) no-repeat 100% 50%;
}
#uploadmaskfield{
width:132px;
}
HTML with "small" JQuery help:
<div class="uploadmask">
<input id="uploadmaskfield" type="text" name="uploadmaskfield">
</div>
<input id="uploadtruefield" type="file" onchange="$('#uploadmaskfield').val(this.value)" >
Just be sure that maskfied is covered compeltly by true upload field.
You can do this as per answer from Open File Dialog box on <a> tag
<input type="file" id="upload" name="upload" style="visibility: hidden; width: 1px; height: 1px" multiple />
Upload
I found that if input(file) is outside form, then firing click event invokes file dialog.
Hopefully this helps someone - I spent 2 hours banging my head against it:
In IE8 or IE9, if you trigger opening a file input with javascript in any way at all (believe me I've tried them all), it won't let you submit the form using javascript, it will just silently fail.
Submitting the form via a regular submit button may work but calling form.submit(); will silently fail.
I had to resort to overlaying my select file button with a transparent file input which works.
This worked for me:
<script>
function sel_file() {
$("input[name=userfile]").trigger('click');
}
</script>
<input type="file" name="userfile" id="userfile" />
Click
it's not impossible:
var evObj = document.createEvent('MouseEvents');
evObj.initMouseEvent('click', true, true, window);
setTimeout(function(){ document.getElementById('input_field_id').dispatchEvent(evObj); },100);
But somehow it works only if this is in a function which was called via a click-event.
So you might have following setup:
html:
<div onclick="openFileChooser()" class="some_fancy_stuff">Click here to open image chooser</div>
<input type="file" id="input_img">
JavaScript:
function openFileChooser() {
var evObj = document.createEvent('MouseEvents');
evObj.initMouseEvent('click', true, true, window);
setTimeout(function()
{
document.getElementById('input_img').dispatchEvent(evObj);
},100);
}
You can use
<button id="file">select file</button>
<input type="file" name="file" id="file_input" style="display:none;">
<script>
$('#file').click(function() {
$('#file_input').focus().trigger('click');
});
</script>
To do so you can click an invisible, pass-through element over the file input :
function simulateFileClick() {
const div = document.createElement("div")
div.style.visibility = "hidden"
div.style.position = "absolute"
div.style.width = "100%"
div.style.height = "100%"
div.style.pointerEvents = "none"
const fileInput = document.getElementById("fileInput") // or whatever selector you like
fileInput.style.position = "relative"
fileInput.appendChild(div)
const mouseEvent = new MouseEvent("click")
div.dispatchEvent(mouseEvent)
}
