I want to hide text in a div after a certain number of characters, and limit it on a word. I found this solution: jquery limit text by length but it does not have a way to close the div back up or break on a word.
This is what I've got so far... This allows me to open and close a div. But I want it to be different in that I want it to check 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 have to add this to thousands of nodes. So I can't go through each one and add the show/hide span that is in this example
<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 showStuff(id) {
document.getElementById(id).style.display = 'block';
}
function hideStuff(id) {
document.getElementById(id).style.display = 'none';
}
</script>
<style type="text/css">
span.read-more { cursor: pointer; color: red; }
span.more { display: none; }
</style>
</head>
<body>
<p><a href="#" onclick="showStuff('answer1'); return false;">What price are your apples?</a><br>
<span id="answer1" style="display: none;">Our apples are 30 pence each. If you buy 10 or more we can sell them at a discounted bulk rate of 25 pence each.
<a href="#" onclick="hideStuff('answer1'); return false;">Close</a><br>
</span></p>
</body>
</html>
I found this on an answer to a different question, but I don't know how to merge the two sets of functionality:
<script type="text/javascript" charset="utf-8">
$(开发者_如何学Cfunction(){
var $elem = $('p'); // The element or elements with the text to hide
var $limit = 10; // 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>'; // Recompose the string with the span tag wrapped around the hidden part of it
$elem.html($str); // Write the string to the DOM
})
</script>
You can easily do something like this:
if ($(".yourelement").html().length > 50) { // if count is greater than 50
$(".yourelement").slideUp("slow");
}
