Can i hide text in a DIV after a number of characters with jQuery?
So far I think it would go something like this - jQuery would cycle through the text until it gets to a certain number of characters. It would then wrap a DIV from that position to the end of the text which could then be hidden with the hide() method. I'm not sure how to insert that wrapping text.
Any other way around this would also be appreciated.
Thanks.
If you put a onkeydown event handler on the body tag you can then count the length in the div of interest, and then you can hide it when done, and remove your event handler.
I am replacing my original answer with this one.....
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
$(function() {
var limit = 20;
var chars = $("#myDiv").text();
if (chars.length > limit) {
var visiblePart = $("<span> "+ chars.substr(0, limit-1) +"</span>");
var dots = $("<span class='dots'>... </span>");
var hiddenPart = $("<span class='more'>"+ chars.substr(limit-1) +"</span>");
var readMore = $("<span class='read-more'>Read More</span>");
readMore.click(function() {
$(this).prev().remove(); // remove dots
$(this).next().show();
$(this).remove(); // remove 'read more'
});
$("#myDiv").empty()
.append(visiblePart)
.append(dots)
.append(readMore)
.append(hiddenPart);
}
});
</script>
<style type="text/css">
span.read-more { cursor: pointer; color: red; }
span.more { display: none; }
</style>
</head>
<body>
<div id="myDiv">Here are all<br/> my characters.<br/> I would like to limit them to 20.</div>
</body>
</html>
This will hide a part of the text
