jquery limit text by length
Can i hide text in a DIV after a number of characters with jQuery?
So far I think it would go something lik开发者_StackOverflowe 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.
I think the purpose can be solved much more easier way than explained above
$(function(){
$(".title").each(function(i){
len=$(this).text().length;
if(len>10)
{
$(this).text($(this).text().substr(0,10)+'...');
}
});
});
The above jquery code will hide div text if it exceeds 10 characters as well as ads ... at the end to explain that there is something more.
This will hide a part of the text

Jeff I was having the same issue wanted to add the text limiter to a dynamic content so here is my solution:
// TEXT CHARACTER LIMITER
$(document).ready(function() {
$.fn.textlimit = function()
{
return this.each(function()
{
var $elem = $(this); // Adding this allows u to apply this anywhere
var $limit = 22; // The number of characters to show
var $str = $elem.html(); // Getting the text
var $strtemp = $str.substr(0,$limit); // Get the visible part of the string
$str = $strtemp + '<span class="hide">' + $str.substr($limit,$str.length) + '</span> ...';
$elem.html($str);
})
};
});
// Call the text limiter above
$(document).ready(function() {
$('.someGenericClass .anotherClass').textlimit()
});
$.fn.textlimit = function(limit)
{
return this.each(function(index,val)
{
var $elem = $(this);
var $limit = limit;
var $strLngth = $(val).text().length; // Getting the text
if($strLngth > $limit)
{
$($elem).text($($elem).text().substr( 0, $limit )+ "...");
}
})
};
**how to use**
$("#DivId").textlimit(60);
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>
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.
HTML :
25 is maxlength.
<input type="text" name="Occupation" id="Occupation" value="" placeholder=""
onkeypress="limitKeypress(event,this.value, 25)" class="form-control" required>
Javascript:
function limitKeypress(event, value, maxLength) {
if (value !== undefined && value.toString().length >= maxLength) {
event.preventDefault();
}
}
