How do I get the content of a <span> using jQuery?
How do I get the content 'This is my name' of 开发者_开发百科the span?
<div id='item1'>
<span>This is my name</span>
</div>
I think this should be a simple example:
$('#item1 span').text();
or
$('#item1 span').html();
$("#item1 span").text();
Assuming you intended it to read id="item1", you need
$('#item1 span').text()
$('#item1').text(); or $('#item1').html(); works fine for id="item1"
Since you did not provide an attribute for the 'item' value, I am assuming a class is being used:
<div class='item1'>
<span>This is my name</span>
</div>
alert($(".item span").text());
Make sure you wait for the DOM to load to use your code, in jQuery you use the ready() function for that:
<html>
<head>
<title>jQuery test</title>
<!-- script that inserts jquery goes here -->
<script type='text/javascript'>
$(document).ready(function() { alert($(".item span").text()); });
</script>
</head>
<body>
<div class='item1'>
<span>This is my name</span>
</div>
</body>
You could use id in span directly in your html.
<span id="span_id">Client</span>
Then your jQuery code would be
$("#span_id").text();
Some one helped me to check errors and found that he used val() instead of text(), it is not possible to use val() function in span. So
$("#span_id").val();
will return null.
In javascript wouldn't you use document.getElementById('item1').innertext?
$('span id').text(); worked with me
$('#id span').text() is the answer!
$('#item1 span').html(); Its working with my code
VERY IMPORTANT Additional info on difference between .text() and .html():
If your selector selects more than one item, e.g you have two spans like so
<span class="foo">bar1</span>
<span class="foo">bar2</span>
,
then
$('.foo').text(); appends the two texts and give you that; whereas
$('.foo').html(); gives you only one of those.
<script>
$(document).ready(function () {
$.each($(".classBalence").find("span"), function () {
if ($(this).text() >1) {
$(this).css("color", "green")
}
if ($(this).text() < 1) {
$(this).css("color", "red")
$(this).css("font-weight", "bold")
}
});
});
</script>
