jquery .children() returning wrong size
I just found the children size not consistent.
Below attach full code with alert, for easy reference.
Is the way I get the data wrong?
<body>
<table width="100" border="0" cellspacing="0" cellpadding="0">
<tr>
<td height="30" valign="top"><strong>Header Title</strong></td>
</tr>
<tr>
<td height="32" valign="top">Date : <strong>01/01/2010 </strong> <br><div><b></b&g开发者_StackOverflowt;</div><span></span></td>
</tr>
</table>
</body>
$("td").each(function() {
alert($(this).children().size());
});
//first td showing 1 direct children- <strong>
//second td showing 4 direct children- <strong> <br> <div> <span>
-----
$("tr").each(function() {
alert($(this).children().size());
});
//first tr showing 1 direct children - <td>
//second tr showing 1 direct children - <td>
-----
$("table").each(function() {
alert($(this).children().size());
});
// ERROR
// this table showing 1 direct children only.... something WRONG.
// I thought there are 2 <tr> inside this table?
The reason is that you don't have a <tbody> within your table. The browser adds this automatically for you, and hence it becomes the only child of <table>.
You may be interested in running this piece of code:
alert($('table').children()[0].tagName);
You're asking the size of the td's children, and in your structure, your td only has one child: the strong tag.
In your second, you are asking the children of your trs. Each of your tr tags only have 1 td, thus it is showing 1 only.
Try this:
alert($("tbody").children().length)
加载中,请稍侯......
