Question

我的标记是一个内部有3个跨度的div。如何使用jquery读取每个span的值。

<div id="mod">
   <span>first span<span>
   <span>second span<span>
   <span>third span<span>
</div>

function getVars(){
  var span1 = ;
  var span2 = ;
  var span3 = ;
}

Answer 1

请试试这个

$('#mod').find('span').text();

Answer 2

        $(document).ready(function(){
            alert($("#mod span:first").text());//First span child only
            alert($("#mod > span").text());// All span children
        });

注意：确保关闭你的范围“”。

Answer 3

您也可以使用此

$(document).ready(function () {
      alert($("#mod span:eq(0)").html());
    });

Answer 4

关闭范围代码<span> first </span>然后它应该有效，所有答案

另一种变体

$(document).ready(function () {
    alert($("#mod").children(":first").text());
});
