Hello I would like the text inside an input element to highlight upon initial click. However my function does not seem to be working. I have researched the issue and seen that there are some issues with jquery 1.7 and below. I have adjusted it to account for this any it still does not work.
Any help would be great. Thanks!
HTML
<input type="text" value="hello"/>
JS
$scope.highlightText = function() {
$("input[type='text']").on("click", function() {
$(this).select();
});

You need to actually call your method at the end of controller, otherwise the event is not bound.
https://plnkr.co/edit/a0BlekB8qTGOmWS8asIx?p=preview
... other code ...
$scope.highlightText = function () {
$("input[type='text']").on("click", function () {
$(this).select();
var test = $(this).parent();
console.log(test);
});
$("textarea").on("click", function () {
$(this).select();
});
};
$scope.highlightText();
};
To select the text inside an input you would simply call this.select() from onclick like shown below
<input type="text" onclick="this.select()" value="hello"/>
I would like to add an onchange event to those input fields without jquery:
<input type="text" id="cbid.wizard.1._latitude">
<input type="text" id="cbid.wizard.1._longitude">
I can already call the object with
<script type="text/javascript">
alert(document.getElementById('cbid.wizard.1._latitude').id);
</script>
In the end, I want to add this behaviour, that if you enter a pair of coordinates into the first input, I will spread the pair over the two input fields?
How do I add an onchange event with javascript?
Ummm, attach an event handler for the 'change' event?
pure JS
document.getElementById('element_id').onchange = function() {
// your logic
};
// or
document.getElementById('element_id').addEventListener(
'change',
callbackFunction,
false
);
jQuery
$('#element_id').change(function() {
// your logic
});
Note
Note, that change event on the text field will be fired after the blur event. It's possible that your looking for keypress event's or something like that.
document.getElementById('cbid.wizard.1._latitude').onchange = function(){
//do something
}
GlobalEventHandlers.onchange docs
or
document.getElementById('cbid.wizard.1._latitude').addEventListener("change", function(){
//do something
});
EventTarget.addEventListener docs
use addEventListener in your window.onload
window.onload=function(){
document.getElementById('cbid.wizard.1._latitude').addEventListener("change", function(){
//do something
});
};
addEventListener
Please try with the below code snippet.
<body>
<input type="text" id="cbid.wizard.1._latitude">
<input type="text" id="cbid.wizard.1._longitude">
<script type="text/javascript">
var txt1 = document.getElementById('cbid.wizard.1._latitude');
txt1.addEventListener('change', function () { alert('a'); }, false);
</script>
</body>
I have a long kind wizard form, like a survey in my site. I want to write a jQuery Function so that when the user click accidentally any link on the page ( except preview and next buttons of the wizard ), it is asked first: are you sure you want to proceed? then it is redirected to the link he clicked, if he click cancel, nothing happens..
So far What i have done is to each link of the page except (next & previw) i have added a class link_ridirect so i can grab all the anchor links. and stop redirecting.
jQuery function is as follow!
<script type="text/javascript">
<!-- HERE IS THE SEARCH FILTER -->
//<![CDATA[
var GLOBAL_NAMESPACE = {};
$(document).ready(function(){
GLOBAL_NAMESPACE.value_changed = true;
});
$(document).ready(function () {
$('.link_redirect').bind('click',function (e) {
e.preventDefault();
if (GLOBAL_NAMESPACE.value_changed){
var res = confirm('you have unsaved changes. Do you want to continue?');
if(res){
window.location.href = $(this).attr('href');
}else{
console.log('stay on same page...');
}
}
});
});
//]]>
</script>
So what i want to do is how can i declare a Global variable to keep track of all field state. So if a field changes, to make it true and call the prevent function.
How about doing this:
$('a').click(function(){return confirm("are you sure?");});
Place it at the bottom of your html, or in the onload of your page, or in the document ready as you suggested in your OP.
edit
If you only want to do this if your variable changesDetected is true, then do it like this:
$('a').click(function(){return !changesDetected || confirm("are you sure?");});
It looks like you have code to interrupt default A-tag clicks already, so the crux of this is to detect when a field has changed such that you want to ask if they want to save before navigating away ?
Here's a JSFiddle Detect Field Changes :
It adds an onchange event to all editable fields whcih sets the global stae to true if something changed.
If the user enters a field then exits without changing, no change is detected.
function setup() {
// bind the change event to all editable fields. Runs on load(or doc ready)
$("input,select").bind("change",function(e) {
GLOBAL_NAMESPACE.value_changed = true;
});
};
you need to use beforeunload event. This event handled when you go out from page.
$(this).on("beforeunload", function () {
return 'are you sure';
});
if you need, that event called not for preview button and next, you can unbind this event handler.
$('#myPreviewButtonId').click(function()
{
console.log('preview clicked');
$(this).unbind("beforeunload");
});
(function($) {
$.fn.checkFileType = function(options) {
var defaults = {
allowedExtensions: [],
success: function() {},
error: function() {}
};
options = $.extend(defaults, options);
return this.each(function() {
$(this).on('change', function() {
var value = $(this).val(),
file = value.toLowerCase(),
extension = file.substring(file.lastIndexOf('.') + 1);
if ($.inArray(extension, options.allowedExtensions) == -1) {
options.error();
$(this).focus();
} else {
options.success();
}
});
});
};
})(jQuery);
$(function() {
$('#image').checkFileType({
allowedExtensions: ['jpg', 'jpeg'],
success: function() {
alert('Success');
},
error: function() {
alert('Error');
}
});
});
label {
display: block;
font-weight: bold;
margin-bottom: 0.5em;
}
<form action="#" method="post" enctype="multipart/form-data">
<div>
<label for="image">Upload image (JPEG only)</label>
<input type="file" name="image" id="image" />
</div>
</form>
You must prevent the default action on a if result of confirm function is false
$(document).ready(function () {
$(".deleteJob").on("click", function (e) {
if (!confirm("Are you Sure want to delete!")) {
e.preventDefault();
}
});
});
I'm trying to trigger an event on an input if the input is clicked or if the input comes in to focus.
The issue i'm having is preventing the event from firing twice on the click as, obviously, clicking on the input also puts it in focus. I've put a very loose version of this on jfiddle to show you what I mean, code as below:
HTML:
<body>
<input type="textbox" name="tb1" class="input1"></input>
<label> box 1 </label>
<input type="textbox" name="tb2" class="input2"></input>
<label> box 2 </label>
</body>
JQuery
$(function () {
$('.input2').click(function() {
alert("click");
});
$('.input2').focus(function() {
alert("focus");
});
});
JSFiddle: http://jsfiddle.net/XALSn/2/
You'll see that when you tab to input2 you get one alert, but if you click you get two. Ideally for my scenario, it needs to be one alert and ignore the other. it also doesn't seem to actually focus.
Thanks in advance for any advice.
How about setting a flag on focus so we can fire on focus and ignore clicks but then listen for clicks on the focussed element too? Make sense? Take a look at the demo jsFiddle - If you focus or click on the unfocussed .index2 it triggers the focus event and ignores the click. Whilst in focus, clicking on it will trigger the click.
I have no idea why you would want this (I cant imagine anyone wanting to click on a focussed element for any reason (because the carat is already active in the field) but here you go:
$(function () {
$('.input2').on("click focus blur", function(e) {
e.stopPropagation();
if(e.type=="click"){
if($(this).data("justfocussed")){
$(this).data("justfocussed",false);
} else {
//I have been clicked on whilst in focus
console.log("click");
}
} else if(e.type=="focus"){
//I have been focussed on (either by clicking on whilst blurred or by tabbing to)
console.log("focus");
$(this).data("justfocussed",true);
} else {
//I no longer have focus
console.log("blur");
$(this).data("justfocussed",false);
}
});
});
http://jsfiddle.net/XALSn/12/
This probably won't be the best answer, but this is a way of doing it. I would suggest adding tab indexes to your inputs and firing the focus event when you blur from another input.
I've added that to this fiddle:
http://jsfiddle.net/XALSn/9/
$(function () {
$('.input2').click(function(e) {
alert("click");
e.preventDefault();
});
});
$('input').blur(function(){
$('input').focus(function() {
alert("focus");
});
});
You can use one thing I am using very often in JS
var doSomething = true;
$(function () {
$('.input2').click(function(e) {
if (doSomething) {
// do something :)
}
doSomething = false;
});
$('.input2').focus(function() {
if (doSomething) {
// do something :)
}
doSomething = false;
});
});
But You have to change value of doSomething on mouseout or foucs over etc. :)
$(function () {
var hasFocus = false;
$("body")
.off()
.on({
click : function()
{
if(!hasFocus)
{
hasFocus = true;
alert("click");
}
},
focus : function()
{
if(!hasFocus)
{
hasFocus = true;
alert("focus");
}
}
},".input2");
});
try setting a flag hasFocus and act accordingly
http://jsfiddle.net/AEVTQ/2/
just add e.preventDefault() on the click event
$(function () {
$('.input2').click(function(e) {
console.log("click");
e.preventDefault();
e.stopPropagation();
});
$('.input2').focus(function() {
console.log("focus");
});
});
If I understand your question right, the e.prevnetDefault() will prevent the browser from automatically focusing on click. Then you can do something different with the click than would with the focus
What is a Vanilla JS or jQuery solution that will select all of the contents of a textbox when the textbox receives focus?
$(document).ready(function() {
$("input:text").focus(function() { $(this).select(); } );
});
<input type="text" onfocus="this.select();" onmouseup="return false;" value="test" />
$(document).ready(function() {
$("input[type=text]").focus().select();
});
$(document).ready(function() {
$("input:text")
.focus(function () { $(this).select(); } )
.mouseup(function (e) {e.preventDefault(); });
});
jQuery is not JavaScript which is more easy to use in some cases.
Look at this example:
<textarea rows="10" cols="50" onclick="this.focus();this.select()">Text is here</textarea>

This is not just a Chrome/Safari issue, I experienced a quite similar behavior with Firefox 18.0.1. The funny part is that this does not happen on MSIE! The problem here is the first mouseup event that forces to unselect the input content, so just ignore the first occurence.
$(':text').focus(function(){
$(this).one('mouseup', function(event){
event.preventDefault();
}).select();
});
The timeOut approach causes a strange behavior, and blocking every mouseup event you can not remove the selection clicking again on the input element.
HTML :
var textFiled = document.getElementById("text-filed");
textFiled.addEventListener("focus", function() { this.select(); });
Enter Your Text : <input type="text" id="text-filed" value="test with filed text">
Using JQuery :
$("#text-filed").focus(function() { $(this).select(); } );
Using React JS :
In the respective component -
<input
type="text"
value="test"
onFocus={e => e.target.select()}
/>
my solution is to use a timeout. Seems to work ok
$('input[type=text]').focus(function() {
var _this = this;
setTimeout(function() {
_this.select();
}, 10);
});
This will also work on iOS:
<input type="text" onclick="this.focus(); this.setSelectionRange(0, 9999);" />

I know inline code is bad style, but I didn't want to put this into a .js file.
Works without jQuery!
<input type="text" value="blah blah" onfocus="this.select(); this.selAll=1;" onmouseup="if(this.selAll==0) return true; this.selAll=0; return false;"></input>
The answers here helped me up to a point, but I had a problem on HTML5 Number input fields when clicking the up/down buttons in Chrome.
If you click one of the buttons, and left the mouse over the button the number would keep changing as if you were holding the mouse button because the mouseup was being thrown away.
I solved this by removing the mouseup handler as soon as it had been triggered as below:
$("input:number").focus(function () {
var $elem = $(this);
$elem.select().mouseup(function (e) {
e.preventDefault();
$elem.unbind(e.type);
});
});
Hope this helps people in the future...
This will work, Try this -
<input id="textField1" onfocus="this.select()" onmouseup="return false" />
Works in Safari/IE 9 and Chrome, I did not get a chance to test in Firefox though.
I know there are already a lot of answers here - but this one is missing so far; a solution which also works with ajax generated content:
$(function (){
$(document).on("focus", "input:text", function() {
$(this).select();
});
});
Like #Travis and #Mari, I wanted to autoselect when the user clicked in, which means preventing the default behaviour of a mouseup event, but not prevent the user from clicking around. The solution I came up with, which works in IE11, Chrome 45, Opera 32 and Firefox 29 (these are the browsers I currently have installed), is based on the sequence of events involved in a mouse click.
When you click on a text input that does not have focus, you get these events (among others):
mousedown: In response to your click. Default handling raises focus if necessary and sets selection start.
focus: As part of the default handling of mousedown.
mouseup: The completion of your click, whose default handling will set the selection end.
When you click on a text input that already has focus, the focus event is skipped. As #Travis and #Mari both astutely noticed, the default handling of mouseup needs to be prevented only if the focus event occurs. However, as there is no "focus didn't happen" event, we need to infer this, which we can do within the mousedown handler.
#Mari's solution requires that jQuery be imported, which I want to avoid. #Travis's solution does this by inspecting document.activeElement. I don't know why exactly his solution doesn't work across browsers, but there is another way to track whether the text input has focus: simply follow its focus and blur events.
Here is the code that works for me:
function MakeTextBoxAutoSelect(input)
{
var blockMouseUp = false;
var inputFocused = false;
input.onfocus =
function ()
{
try
{
input.selectionStart = 0;
input.selectionEnd = input.value.length;
}
catch (error)
{
input.select();
}
inputFocused = true;
};
input.onblur =
function ()
{
inputFocused = false;
};
input.onmousedown =
function ()
{
blockMouseUp = !inputFocused;
};
input.onmouseup =
function ()
{
if (blockMouseUp)
return false;
};
}
I hope this is of help to someone. :-)
I was able to slightly improve Zach's answer by incorporating a few function calls. The problem with that answer is that it disables onMouseUp completely, thereby preventing you from clicking around in the textbox once it has focus.
Here is my code:
<input type="text" onfocus="this.select()" onMouseUp="javascript:TextBoxMouseUp();" onMouseDown="javascript:TextBoxMouseDown();" />
<script type="text/javascript">
var doMouseUp = true;
function TextBoxMouseDown() {
doMouseUp = this == document.activeElement;
return doMouseUp;
}
function TextBoxMouseUp() {
if (doMouseUp)
{ return true; }
else {
doMouseUp = true;
return false;
}
}
</script>
This is a slight improvement over Zach's answer. It works perfectly in IE, doesn't work at all in Chrome, and works with alternating success in FireFox (literally every other time). If someone has an idea of how to make it work reliably in FF or Chrome, please share.
Anyway, I figured I'd share what I could to make this a little nicer.
What is a JavaScript or jQuery solution that will select all of the contents of a textbox when the textbox receives focus?
You only need to add the following attribute:
onfocus="this.select()"
For example:
<input type="text" value="sometext" onfocus="this.select()">
(Honestly I have no clue why you would need anything else.)
This worked for me (posting since it is not in answers but in a comment)
$("#textBox").focus().select();
onclick="this.focus();this.select()"
$('input').focus(function () {
var self = $(this);
setTimeout(function () {
self.select();
}, 1);
});
Edit: Per #DavidG's request, I can't provide details because I'm not sure why this works, but I believe it has something to do with the focus event propagating up or down or whatever it does and the input element getting the notification it's received focus. Setting the timeout gives the element a moment to realize it's done so.
If you chain the events together I believe it eliminates the need to use .one as suggested elsewhere in this thread.
Example:
$('input.your_element').focus( function () {
$(this).select().mouseup( function (e) {
e.preventDefault();
});
});
Note: If you are programming in ASP.NET, you can run the script using ScriptManager.RegisterStartupScript in C#:
ScriptManager.RegisterStartupScript(txtField, txtField.GetType(), txtField.AccessKey, "$('#MainContent_txtField').focus(function() { $(this).select(); });", true );
Or just type the script in the HTML page suggested in the other answers.
I sow this one some where , work perfectly !
$('input').on('focus', function (e) {
$(this)
$(element).one('mouseup', function () {
$(this).select();
return false;
}) .select();
});
I'm kind of late to the party, but this works perfectly in IE11, Chrome, Firefox, without messing up mouseup (and without JQuery).
inputElement.addEventListener("focus", function (e) {
var target = e.currentTarget;
if (target) {
target.select();
target.addEventListener("mouseup", function _tempoMouseUp(event) {
event.preventDefault();
target.removeEventListener("mouseup", _tempoMouseUp);
});
}
});
My solution is next:
var mouseUp;
$(document).ready(function() {
$(inputSelector).focus(function() {
this.select();
})
.mousedown(function () {
if ($(this).is(":focus")) {
mouseUp = true;
}
else {
mouseUp = false;
}
})
.mouseup(function () {
return mouseUp;
});
});
So mouseup will work usually, but will not make unselect after getting focus by input
