i具有使用PHP和HTML的动态表排。
我使用了使用jQuery的JQuery创建的JavaScript。form.submit（），但这里的问题是，每当我单击表上的任何行时，它都只会解析最后一行的值。
如何解决这个问题？
代码看起来像这样：
'<tr onclick="submit()"><td><input type="hidden" name="a" value='.$a.' /><input type="hidden" name="b" value='.$b.' />'.$aid.'</td></tr>';
这是每行循环的，并且是在回声语句中。基本上正常工作。关于如何解决这个问题的任何想法。我可以解决这个问题。关于我如何做的任何解决方案都非常感谢。
谢谢
将您的html更改为：
'<tr onclick="submit(this)"><td><input type="hidden" name="a" value='.$a.' /><input type="hidden" name="b" value='.$b.' />'.$aid.'</td></tr>';
function submit(el) {
var es = $(el).find("[name=a]").val();
alert(es);
}
