I have a div that I need to grab the HTML contents of (so naturally I use html())...
However, they are text fields. Whenever I grab the contents of the div (that contains the text fields), it grabs the initial HTML and not any data changed by the end user...
Here is JS bin version..change the input field, run the function and you see that it will only take the initial value of the field...
Any way around this?

Try this out ^
The code:
$(document).ready(function() {
$('div#top input').change(function() {
$(this).attr('value', $(this).val());
});
$('#click').click(function() {
var _curHtml = $("div#top").html();
$("div#bottom").html(_curHtml);
});
});
Your getting the HTML of the div. You want to get the value of the input box:
$(document).ready(function() {
$('#click').click(function() {
var _curHtml = $("#data").val();
$("div#bottom").html(_curHtml);
});
});
No way to do it with html(). You'll have to get the value of each input using val(). You can use
$("input").each(function() {
doSomething($(this).val());
}
if it make life easier.
$(document).ready(function() {
$('#click').click(function() {
var _curHtml = $("#data").val();
$("div#bottom").html(_curHtml);
});
});
The easiest hack would be like this:
$("div#bottom input").val($("div#top input").val());
Get the value of the updated input and set that to the clone.

$(document).ready(function() {
$('#data').change(function() {
$(this).attr('value', $(this).val());
})
$('#click').click(function() {
var _curHtml = $("div#top").html();
$("div#bottom").html(_curHtml);
});
});
This works.. here's the link http://jsbin.com/oleni3/2/edit
UPDATE: If you have many inputs inside the div, you can use this http://jsbin.com/oleni3/6/edit

I need to get element value of #answer_comment and show it inside input with id #comment
$(document).ready(function() {
$("body").on("click", "#answer_comment", function(e) {
var answer = document.getElementById('answer_comment').val();
$('#comment').val(answer);
})
what is wrong?
Also if possible, how to create a cookie with the selected value?
Hope this is what you are looking for since it is a span you can get the value using attr('value')
$("body").on("click", "#answer_comment", function(e) {
var answer = $('#answer_comment').attr('value');
$('#comment').val(answer);
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<span id = "answer_comment" value="username">click here</span>
<input id="comment">
you are mixing jQuery with vanilla JS. You should pick a horse and stick to it. Pure JQ would be
$(document).ready(function() {
$("body").on("click", "#answer_comment", function(e) {
var answer = $('#answer_comment').text();
$('#comment').val(answer);
})
I want to remove the headers befor i expor the data into excel, hide doesnt work because the data is still there, so i was using remove. but once removed, after the exporting to excel is completed i wanted to undo the removed headers for display.
<script type="text/javascript">
$("#btnExport").click(function(e) {
alert("");
$head=$('tr.header');
$div=$('#dvData')
$div.remove('tr.header');
alert();
window.open('data:application/vnd.ms-excel,' +encodeURIComponent($div.html()));
e.preventDefault();
});
</script>
i was trying to save the div object in a variable process on that variable div and send it, bt the div sent shows no changes!!
Just make a clone, remove whatever you want, and get the HTML
$("#btnExport").click(function(e) {
e.preventDefault();
var div = $('#dvData'),
clone = div.clone();
clone.find('tr.header').remove();
window.open('data:application/vnd.ms-excel,' + encodeURIComponent( clone.html() ));
});
append saved variable to parent of the deleted div.
Add it before the target element...remove it post that...
$(function() {
$('#add').click(function(){
var div = $('div.toRemove');
var newDiv = $('<div/>').addClass('added').html('hello world');
//newDiv.prependTo(div);
div.before(newDiv);
this.disabled = true;
div.remove();
});
$('#reset').click(function(){
$('div').remove();
$(document.body).append($('<div/>').addClass('toRemove').html('toremove'));
$('#add').removeAttr('disabled');
});
});
Fiddle: http://jsfiddle.net/deostroll/wnu9pv9y/
First of all, You must use var for each variable such as $head and $div
You can use clone to achieve the desired result.
$("#btnExport").click(function(e) {
var $clonedDiv = $('#dvData').clone(true);
$clonedDiv.find("tr.header");
window.open('data:application/vnd.ms-excel,' +encodeURIComponent($clonedDiv.html()));
e.preventDefault();
});
</script>
use clone(true) to retain the events
As per understanding you first want to remove the header before export and then want to add to the table as it is. if i am properly understanding your requirement try the following
$("#btnExport").click(function (e) {
alert("");
$div = $('#dvData')
$divToRemain = $div.find('#TableId thead')
$div.find('#TableId thead').remove();
window.open('data:application/vnd.ms-excel,' + encodeURIComponent($div.html()));
$divToRemain.appendTo('#tblHoliday');
e.preventDefault();
});
Here i save the removed header in the variable and after export i appended it to the table.
Hope this will help.
I facing problem with my jquery, on showing input text based on input value.
Here is the JS fiddle demo :
http://jsfiddle.net/Ltapp/364/
When I try to input #hotmail, the input box will show. But when I want to type some text in the #hotm input box, it will hide again.
JS code :
$(window).load(function(){
var myString = '#hotmail';
$('#hotm').hide();
$("input").keyup(function () {
var value = $(this).val();
if($(this).val().match(myString)) {
$('#hotm').show();
} else {
$('#hotm').hide();
}
});
});
It's because your selector $("input") affects both input elements. I have updated it to the $("input:first") selector instead. JsFiddle here
$("input:first").keyup(function () {
var value = $(this).val();
if(value.match(myString)) {
$('#hotm').show();
} else {
$('#hotm').hide();
}
});
As many has said, you are binding the event on all the inputs I did a little change:
$(function(){
var myString = /#hotmail/ig;
$("#check").bind('keyup checkvalue', function() {
$('#hotm')[myString.test(this.value) ? 'show' : 'hide']();
}).trigger('checkvalue');
});
using regex if you are using #HoTmAil it will also hit on that, and also added a custom event checkvalue to see if #hotm should be visible on for example a postback on the form you might be using.
demo: http://jsfiddle.net/voigtan/xjwvT/1/
You're affecting all inputs. Either give each one a unique ID / Class or use the jQuery $(this) method.
See JSFiddle Here:
http://jsfiddle.net/Ltapp/366/
<input type="text" id="firstinput"/>
<p id="secondinput"><input type="text"/></p>
var myString = '#hotmail';
$('#secondinput').hide();
$("#firstinput").keyup(function () {
var value = $(this).val();
if($(this).val().match(myString)) {
$('#secondinput').show();
} else {
$('#secondinput').hide();
}
});
use this for your if part :
if($(this).val().match($(this).val().substr(0,strlen($(this).val())))
it's because the new box also = "input"; if you give the hotmail textbox it's own id, it won't hide
<input id="hotmail" type="text"/>
and then
$("#hotmail").keyup(function () {...});
How can I build a simple table filter with good effect using jQuery? I don't mind about pagination.
list -> select data of database.
I do not want to use a plugin, I prefer the use of short code.
Example:
$('#inputFilter').keyup(function() {
var that = this;
$.each($('tr'),
function(i, val) {
if ($(val).text().indexOf($(that).val()) == -1) {
$('tr').eq(i).hide();
} else {
$('tr').eq(i).show();
}
});
});
CHECH THIS
I don't normally help out with this, but I got bored this morning..
http://jsfiddle.net/hHJxP/
I know it's kinda late but hope this code helps.
<script>
$(document).ready(function(){
$("#yourInput").on("keyup", function() {
var value = $(this).val().toLowerCase();
$("#yourTableId tr").filter(function() {
$(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
});
});
});
</script>
Try testing the innerHTML of the row to the value of the input field, showing / hiding the content depending on the test-result.
$('#test').bind('keyup', function() {
var s = new RegExp(this.value);
$('tr').each(function() {
if(s.test(this.innerHTML)) $(this).show();
else $(this).hide();
});
});
JSFIDDLE with example table and input field.
edit
It might be better to use .text() instead of innerHTML. Performancewise innerHTML would be better, but .text() doesn't accept the html-tags as valid search results. JSFIDDLE #2.
This is probably stupidity on my part, but where am I going wrong with this?
$(function() {
$('textarea#comment').each(function() {
var $txt = $(this).val();
$(this).bind('focus', function() {
if($(this).val($txt)) {
$(this).val('');
}
});
});
});
Basically on focus I want to check if the value is the default value in this case 'Enter your comment', then if it is change the value to nothing.
Anyone know how to do this? I'm guessing its relatively simple. What the code does at the moment is removes any value.
Ok first off you should only have one tag with the id of comment since ids are supposed to be unique, but if we go with your code you have to setup a default value first like this:
<textarea id="comment">Enter text here</textarea>
Now the javascript:
(function() {
$('textarea#comment').each(function() {
var $txt = $(this).val();
//alert($txt);
$(this).bind('focus', function() {
if($(this).val() === this.defaultValue) {
$(this).val('');
}
});
});
})();
The self executing function syntax has been corrected here and should be as follow:
(function () { // my code here })();
and for default value use:
this.defaulValue; // works for input boxes as well
Hope it helps. Cheers
jquery_example plugin do exactly what you need. You may have a look at its source code and get some inspiration. Or you can store the default value as meta-data on the tag and check against it on change event of the textarea tag.
try
$('#comment').live('click change focus', function() {
var $txt = $(this).val();
if($txt == 'Enter your comment' );
$(this).val('');
});
