Unfortunately my front end skills are lacking as my role puts me more on the server side / db technologies as opposed to css / js. In any event, I am trying to implement this:
https://github.com/blueimp/jQuery-File-Upload/wiki/Complete-code-example-using-blueimp-jQuery-file-upload-control-in-Asp.Net.
And more specifically I was able to find an asp.net example here:
http://www.webtrendset.com/2011/06/22/complete-code-example-for-using-blueimp-jquery-file-upload-control-in-asp-net/
Basically allowing you to do mass image uploads.
I've set up the front end with the correct css and js files. I had to modify some of the js files to make use of on() instead of live() as live is deprecated. My form loads and looks like the following:
So far so good, however, as soon as I "Add file" or drag and drop a file chrome developer tools tells me the following:
Uncaught TypeError: Cannot read property '_adjustMaxNumberOfFiles' of undefined
It specifies the file as jquery.fileupload-ui.js and more specifically points me to this:
var that = $(this).data('fileupload');
that._adjustMaxNumberOfFiles(-data.files.length);
I alerted that and of course it seems to be undefined...But I don't know enough jquery to understand why it is undefined. My fileupload div markup was as follows:
<div id="fileupload">
<form action="/Handler.ashx" method="POST" enctype="multipart/form-data">
<div class="fileupload-buttonbar">
<label class="fileinput-button">
<span>Add files...</span>
<input id="file" type="file" name="files[]" multiple>
</label>
<button type="submit" class="start">Start upload</button>
<button type="reset" class="cancel">Cancel upload</button>
<button type="button" class="delete">Delete files</button>
</div>
</form>
<div class="fileupload-content">
<table class="files"></table>
<div class="fileupload-progressbar"></div>
</div>
</div>
So what could be causing this to be undefined? This is what _adjustMaxNumberOfFiles does
_adjustMaxNumberOfFiles: function (operand) {
if (typeof this.options.maxNumberOfFiles === 'number') {
this.options.maxNumberOfFiles += operand;
if (this.options.maxNumberOfFiles < 1) {
this._disableFileInputButton();
} else {
this._enableFileInputButton();
}
}
},
I'm using jquery 2.0.3 and jquery ui 1.10.3
Update
I've gotten it down to the point that the example link which I posted (2nd link above) the only difference is the version of jquery they are using, appears to be 1.8.2 and I am using 2.0.3. The difference and problem is this piece of code:
var that = $(this).data('fileupload');
In the example download this returns some strange object:
a.(anonymous function).(anonymous function) {element: e.fn.e.init[1], options: Object, _sequence: Object, _total: 0, _loaded: 0…}
In my version (using 2.0.3) I am getting undefined for this:
var that = $(this).data('fileupload');
Is there another way I can do this one line of code?
After much playing around in the console window I got it with this:
var that = $("#fileupload").data('blueimpUI-fileupload');
So for anyone that is using anything > jQuery 1.8 please change this line:
var that = $(this).data('fileupload');
to this:
var that = $("#fileupload").data('blueimpUI-fileupload');
How are you initializing the plugin? The issue might be your selector. Target the form itself, vs. the wrapping div.
Based on your html...
Try changing: $('#fileupload').fileupload({ /*options*/ });
To: $('#fileupload form').fileupload({ /*options*/ });
Also, you may have to move your .fileupload-content div inside of the form tag as well.

Would like to get a pure Javascript solution for my situation.
My HTML and JS is as follows. But the HTML can't be manipulated unfortunately as its on SP.
function getCurrentValue() {
var searchQuery = document.getElementById("SearchBox").children[0].children[0].value;
console.log(searchQuery);
}
<div id="SearchBox">
<div id"randomGeneratedId">
<input type="text" value="Search..." id="anotherRandomGeneratedId"/>
</div>
</div>
<br/>
<input type="button" value="Run!" onClick="getCurrentValue();">
The JS above works in the snippet here but on my page it returns the default value of the input ie. "Search..."
FYI its running on SharePoint 2013. I should note that I managed to get it to work when getElementId("anotherRandomGeneratedId") but that require writing a custom script for every page.
Have a try to modify getCurrentValue() to:
function getCurrentValue() {
var searchQuery = document.querySelector("#SearchBox input").value;
console.log(searchQuery);
}
I'm creating a small quiz type application in javascript. My html structure looks like this.
<div class="btn-group-toggle" data-toggle="buttons">
<label class="btn btn-secondary btn-insight" data-target="#myCarousel" data-responseID="1">
<input type="radio" name="options" id="option1" autocomplete="off">
<h5>1</h5>
<p class="mb-0">label for 1</p>
<div class="line-bottom gradient-purple"></div>
</label>
...
</div>
I'm trying to use the custom data attribute data-responseID to determine what answer was provided by the user.
When the program starts, loop through the labels using querySelectorAll and attaching a click listener to each one.
const responseLables = document.querySelectorAll('div.btn-group-toggle > label');
responseLables.forEach(element => {
element.addEventListener('click', function(e){
const clickedResponse = element.attributes[2].value;
determineWhereToSlide(clickedResponse);
});
});
This works well in Firefox and Chrome, but doesn't in Edge. (I'm not concerned with IE 11)
determineWhereToSlide is just a function that gives an alert for now. Eventually it'll be used to push the carousel forward.
I've made a working example and you can see the issue if you open it up in different browser.

I don't get why this is happening.
*EDIT 1
I just realized that the order of the attributes are different. If you change the index value to ...attributes[1]... then it works just fine. Is there a better way to do this rather than providing an index?
Don't refer to attributes by index (even if it seems it should work, attributes were unordered at least until DOM3). Use any of:
element.getAttributeNode("data-responseID").value
element.attributes["data-responseID"].value
element.getAttribute("data-responseID")
element.dataset.responseID
You can use the getAttribute() method.
replace this
const clickedResponse = element.attributes[2].value;
to this
const clickedResponse = element.getAttribute('data-responseID')
I have a search box that needs to be within a form so that it can post to another page for a search functionality to work.
I originally had this working fine in Firefox by using an iFrame, but using the search box would simply refresh the when using Internet Explorer.
I found out that it worked fine if I simply created another form underneath the current one, however this obviously leaves it in the wrong place on the page.
I attempted to use the jQuery clone() method that I have succesfully used elsewhere on the site, but this is refusing to work.
I looked around and found another way of using the clone() method and I have it working fine within jsfiddle, but it will not work on my site.
This is the div that I want to populate:
<div id="CustomerSearch">
2
</div>
And this is the div that I want to be cloned:
<form name="frmCustomerList" action="../CustomerList/default.asp" method="post">
<div id="CustomerSearchClone">
1
Customer Search: <br />
<input type="text"id="txtSearch" name="txtSearch" class="Searchbox" />
<input type="submit" value="View" name="txtSearchSubmit" />
</div>
</form>
This is the script that I am using in an external file:
var CustomerSearch = jQuery('#CustomerSearch');
var CustomerSearchClone = jQuery('#CustomerSearchClone');
CustomerSearch.html(CustomerSearchClone.clone(true));
I have it working in JSFiddle here: http://jsfiddle.net/de9kc/92/
Any ideas?
Thanks guys
I'm not a .NET guy but the div you are pasting too is still within a form tag so I'm not certain that this wouldn't cause a hiccup for .NET at submission time (or postback, or whatever).
However, with respect to getting the cloned form elements where you wanted them per the layout you demonstrate in your question;
I modified the pre-result html like so:
//html
<form id="form1" runat="server">
<div id="CustomerSearch">2 Customer Search:</div>
</form>
<form name="frmCustomerList" action="../CustomerList/default.asp" method="post">
<div id="CustomerSearchClone">1 Customer Search:
<br />
<input type="text" id="txtSearch" name="txtSearch" class="Searchbox" />
<input type="submit" value="View" name="txtSearchSubmit" />
</div>
</form>
then i used this jQuery:
// the vars you already created
var CustomerSearch = jQuery('#CustomerSearch');
var CustomerSearchClone = jQuery('#CustomerSearchClone');
// using .clone(true, true) for deepWithDataAndEvents - not sure if you want this?
// will the .clone(true, true) retain input's link to original form id? I'm uncertain
// using .children() because clone's intended destination already has a div container
CustomerSearchClone.children().clone(true, true).appendTo(CustomerSearch);
// hide clone's source after cloning; no sense in having both search boxes visible
CustomerSearchClone.hide();
Note: Using .clone() has the side-effect of producing elements with duplicate id attributes, which are supposed to be unique. (per http://api.jquery.com/clone/)
But you are appending the cloned elements into a different form tag, so maybe a non-issue.
I'm just learning jQuery myself, but I thought I would give the solution a shot ;-$

I have a file upload field,that is,<s:file> </s:file>. And I have a button "clear". On clicking this button, the field which has some file link should become empty.Could anyone help me with this?
My code:
<s:file id="filetestplanid2" name="testPlanDto.testFile" label="test"
tooltipIconPath="../../KY/images/common/buttons/uploadBtn.png"
title="Browse" tooltip="Browse..." cssClass="file" />
My javascript:
$('#filetestplanid2').val(null);
$('#filetestplanid2').val("");
I tried these but no luck.
Also tried:
var file = $("#filetestplanid2"); file.replaceWith(file = file.clone(true));
$('#filetestplanid2').html( $('#filetestplanid2').html() );
Assuming
<input type="button" onclick="clearFileElement('filetestplanid2');" />
Vanilla JS
function clearFileElement(fileId){
document.getElementById(fileId).value = '';
};
Demo: http://jsfiddle.net/2nxGr/
Can't make it works with jQuery but basically you have to substitute it with a clone of itself (with all the properties, gained using clone(true)).
Just stick to the plain JS version, it works like a charm.
EDIT
I've found now a very smart solution that works on every browser: https://stackoverflow.com/a/13351234/1654265
You can make it empty using Jquery too, just like this:
$("#filetestplanid2")[0].value = ""
or
$("#filetestplanid2").get(0).value = ""
I have this snippet of HTML:
<div class="clearfix" id="menu-file-div">
<label id="menu-file-label" for="id_menu_file">From File</label>
<div class="input">
<div id="file-upload">
<input type="hidden" name="menu_file" id="id_menu_file" />
<script type="text/javascript">var field_id = "id_menu_file";</script>
<script type="text/javascript">var append_to_element_id = "menu-upload";</script>
<script type="text/javascript">var loader_element_id = "newmenu-modal";</script>
<noscript>
<p>Please enable JavaScipt to upload a file.</p>
</noscript>
</div>
</div>
</div>
In my console, when I try to use the jquery id selector, it fails to return the input element:
> $("#id_menu_file")
[]
Any thoughts on why this is so? I feel like I'm missing something simple. Thank you!
EDIT - some other javascript was removing the element, that is why it's not showing up. Thanks all for your help.
To repeat my first answer (which may be applicable to others reading this post later, and which was deleted despite the fact that it "fundamentally answer[ed] the question"):
Is this HTML inside of a frame (iframe or regular)? That could make it difficult for jQuery to find your element, unless you give it the right context.
To add a context to a jQuery selector you just provide that context as an extra argument, for example: $('TD', aFrameElement);
If the element in question is not inside a frame (which is the case for zallarak), the problem is almost certainly a timing issue: the jQuery selection is happening before the element has gotten loaded on the page. You can test this theory by adding the following code (anywhere):
$(function(){
console.log($("#id_menu_file"))
});
If that is the problem, simply wrap your code in $(function(){ to fix matters.
try :
$("#id_menu_file").get(0)
$(selector) return arrays
