Storing variable via .text() isn't uptodate - javascript

I have <span> tags in a div that is removed when user clicks on them. Works fine.
I want to store the .text() inside that div in a variable. The problem is that the updated text doesn't get stored.
Click on a word to remove it in this jsFiddle.
As you can see, the content variable returns the old text, not the new revised one.
How can I store a variable with the updated text?
jQuery:
jQuery(document).ready(function() {
jQuery(document).on("mousedown", ".hello span", function() {
// don't add full stop at the end of sentence if it already ends with
var endChars = [".", "?", "!"];
jQuery(this).fadeOut(function(){
var parentObj = jQuery(this).parent();
jQuery(this).remove();
var text = parentObj.find("span").first().html();
parentObj.find("span").first().html(ta_capitalizeFirstLetter(text));
text = parentObj.find("span").last().html();
if ( endChars.indexOf(text.slice(-1)) == -1 )
{
parentObj.find("span").last().html(text+".");
}
});
var content = jQuery(this).parent().parent().find('.hello').text();
alert(content);
});
});

The code to get the new text should be moved inside the fadeOut callback. Once the animation is completed and element is removed, then the innerText of the parent element will be updated. At this time, the updated content should be read from the DOM.
Demo
// Cache the element
var $el = jQuery(this).parent().parent().find('.hello');
jQuery(this).fadeOut(function () {
jQuery(this).remove();
// Irrelevant code removed from here
...
var content = $el.text();
alert(content);
});
Here's another simple demo with minimal code that'll help to understand the code better.
Demo

I tried to debug your jsfiddle in chrome, and it looks like the priority of your code is like this:
declare on this event - jQuery(this).fadeOut(function(){
get the the current data of the div var content = jQuery(this).parent().parent().find('.hello').text();.
alert your data without changes.
calling the funcntion of fadeout
I think all you have to do is to call your alert and 2 from your anonymous function of fadeout

Just put your alert inside the callback:
jQuery(this).fadeOut(function(){
var parentObj = jQuery(this).parent();
jQuery(this).remove();
var text = parentObj.find("span").first().html();
parentObj.find("span").first().html(ta_capitalizeFirstLetter(text));
text = parentObj.find("span").last().html();
if ( endChars.indexOf(text.slice(-1)) == -1 ) {
parentObj.find("span").last().html(text+".");
var content = parentObj.parent().find('.hello').text();
alert(content);
}
});

Remove innerHTML img completely by jQuery selection

I've dinamically created a div with the code below:
typebox.innerHTML += "<div id='idtypebox' class='typebox'><img id='typeImg' width='30px' height='30px' src="+d[o].src+"></div>";
My intention is to remove completely the innerHTML I created, by changing the innerHTML that had created the img and if change the form A to B, those images will be removed.
function SelectCheck() {
var select_val = $('#Check').val();
// using this to remove typeimg
var toRemove = document.getElementById('typeImg');
toRemove.parentNode.removeChild(toRemove);
if (select_val) {
ajax_json_gallery("Img/"+select_val);
}
return;
}
$(document).ready(function() {
$("#Check").change(SelectCheck).change();
});
I tried this code by on button and it works, but if I put in jQuery selection I get an error
var toRemove = document.getElementById('typeImg');
toRemove.parentNode.removeChild(toRemove);
Why not just :
$("#typeImg").remove();
And the complete code :
function SelectCheck(){
var select_val = $('#Check').val();
// using this to remove typeimg
$("#typeImg").remove();
if(select_val){
ajax_json_gallery("Img/"+select_val);
}
return;
}
jQuery(document).ready(function($) {
myVar=$("#d1 [href]").html();
var href = $(myVar).attr('src');
$("#d1").html('');
$("#d1").html('<img src="'+href+'" class="images_responsive_mode">').removeAttr("href");
});
</script>
this is one of the script which i created for remove the class assigned by wordpress and to assign new class for responsive image , if it useful for you do this !
you can use childNodes to remove the innerHtml
var toRemove = document.getElementById('typeImg');
toRemove.parentNode.removeChild(toRemove.childNodes[0])

JavaScript global array undefined although it shows in alert

I have written a JQuery script in SharePoint to truncate a multiple lines of text column. Below is the script:
<script>
window.$divs = [];
window.$i = 0;
window.textFull = new Array();
$(document).ready(function(){
window.setInterval(function(){
/// call your function here
$divs = $("[class^=ExternalClass]");
for($i=0;$i<$divs.length;$i++)
{
textFull[$i] = $($divs[$i]).html();
if(typeof textFull[$i] != 'undefined' && textFull[$i].length > 50)
{
//alert($textFull[$i]); this alert show the correct text
$($divs[$i]).html(textFull[$i].substring(0,49)+"<a href='javascript:alert(textFull[$i]);'>...more</a>");
}
}
}, 500);
});
</script>​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​
In the above code "javascript:alert(textFull[$i])" shows 'undefined' in alert. But the alert above it shows correct text. Also I when I use a variable instead of an array it works fine in the alert inside anchor tag. I have also declared the array as global. So what am I missing?
You are running into the classic problem using for loop without using a closure to keep track of the index with
No need to create that array if all it is used for is to modify the html
Can do that much simpler using html(fn) and a jQuery event handler
$("[class^=ExternalClass]").html(function(index, oldhtml){
if(oldhtml.length >=50){
// store the full html in element data
$(this).data('html', oldhtml)
return oldhtml.substring(0,49)+"<a class="more-btn">...more</a>"
} else{
return oldhtml
}
}).find('.more-btn').click(function(){
var $div = $(this).parent();
$div.html( $div.data('html'));
});

Using Javascript to hide text shown on currency switch

I'd like to use Javascript (on page load) to remove the wording 'Choose a currency to display the price:'.
Leaving just the currency icons in the box (Div id = currency-switch).
How can I do this?
Page url: http://www.workbooks.com/pricing-page
Image example:
You can remove this text with for example:
window.onload = function(){
var el = document.getElementById("currency-switch");
var child = el.childNodes[0];
el.removeChild(child);
};
If you want to keep it stupid simple just add an span around the text and give it an id like "currency_text".
Then you only need this code:
var elem = document.getElementByid("currency_text");
elem.remove();
Try
$(document).ready(function() {
var currencyDiv = $('#currency-switch');
currencyDiv.innerHTML(currencyDiv.innerHTML().replace("Choose a currency to display the price:", ""));
}
This will remove the text as soon as the DOM is ready.
Please see below which will just remove the text:
This will trigger on page load
<script>
// self executing function here
(function() {
var selected_div = document.getElementById('currency-switch');
var text_to_change = selected_div.childNodes[0];
text_to_change.nodeValue = '';
})();
</script>
Since it's a text node, you could do the following in jQuery. This will be triggered on DOM ready.
$(function() {
jQuery("#currency-switch").contents()
.filter(function() {
return this.nodeType === 3;
}).remove();
});
You can use this code:
var requiredContent = document.getElementById('currency-switch').innerHTML.split(':')[1];
document.getElementById('currency-switch').innerHTML = requiredContent;
See it working here: https://jsfiddle.net/eg4hpg4z/
However, it is not very clean, but should work, if you cant directly modify the html.
A better solution would be to modify your code to move the text content within a span and show hide the text like so:
HTML:
<div id="currency-switch">
<span class="currency-label">Choose a currency to display the price: </span>
<span class="gb-background"><span class="GB"> £ </span></span><span class="es-background"><span class="ES"> € </span></span><span class="au-background"><span class="AU"> $ </span></span></div>
Javascript:
document.getElementsByClassName('currency-label')[0].style.display = 'none';

jQuery hide inner html, except for a tags

I have the following HTML:
<div class="content-body attribute-pdf">
<a href="/_fragment/content/download/296/1935/file/blabla.pdf">
blabla.pdf</a> 1.2 Mb
</div>
This is coming out of a CMS, and I would like to hide this "1.2 MB",but still keep the A href part
is this possible to do in jQuery ?
I tried this:
$(".attribute-pdf").children().hide();
which hides the A href, but still shows the text. I want it vice-versa - hide the text, but still show the A href.
A quick way, in jQuery - empty the div, replace its contents with just the <a> tag:
$('.attribute-pdf').each(
function() {
var container = $(this);
var a = container.find('a').detach();
container.empty().append(a);
}
);
Example: http://codepen.io/paulroub/pen/iaFnK
You could set the contents of the parent to be the contents of the childeren ...
$(".attribute-pdf").each(function(){
var $this = $(this); // cache for performance
$this.html($this.children());
});
grab the content ( a link ) , empty the div ( removes 1.2 mb ) and again append a link.
http://jsfiddle.net/vpVMK/
var content = $(".attribute-pdf a");
$(".attribute-pdf").html('');
$(".attribute-pdf").append(content);
you could do:
// contents() gives children, all including non-element nodes.
// Then, we can filter those down to the final text one.
var textNodes = $( ".attribute-pdf" ).contents().filter(function() {
return this.nodeType === 3;
});
var lastTextNode = textNodes.last();
//and replace
lastTextNode.replaceWith('');
You could do this:
var children = $(".attribute-pdf").children();
$(".attribute-pdf").html(children);
http://jsfiddle.net/H2WVt/
Here is another method that hasn't been posted yet:
$(".attribute-pdf").html(function(){
var $this = $(this),
$tmp = $('<div>');
return $.makeArray( $this.children('a').map(function() {
$tmp.html(this)
return $tmp[0].innerHTML
}) ).join('')
})

How do i clear text out of a div using javascript

Okay here is what i have:
<script type="text/javascript">
var where = document.getElementById("info")
var texts = false;
function clear() {
where.innerHTML = "";
};
function dostuff(what) {
if(where.style.value === ""){
var comm = document.createTextNode(what);
where.appendChild(comm);
}else {
clear();
}
};
</script>
the id "info" is a div
this is basically a vertical navigation bar that shows tooltips in a div under the buttons when you hover over them.
So I want to first check if the div has no value then if it doesn't then it will append text into it, else it will clear the text but i also want it to append the text after it clears. I'm not sure how to do this and help would be appreciated. thanks
Since you want to clear the item anyways and put your new text in, why even bothering with the conditional? You could just as easily do:
function dostuff(what) {
where.innerHTML = what;
};
Working example
