javascript - 如何在javascript中调用jQuery插件类

我想使用Tablesort jQuery插件对表进行排序。

我的html有一个select标记，它在更改任何选项时会从my.js调用searchXML（）函数。

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
</head>
<body>
    Select an option:
    <select onchange="searchXML()" id="input">
      <option></option>
      <option value="milk">Milk</option>
      <option value="tea">Tea</option>
      <option value="sugar">Sugar</option>
      <option value="juice">Juice</option>
      <option value="all">All</option>
    </select>

    <br />
    <div id="results">
    </div>

    <script src="http://code.jquery.com/jquery-1.11.0.min.js" type="text/javascript" charset="utf-8"></script>
    <script src="js/my.js" type="text/javascript"></script>
    <script src="js/jquery.tablesorter.min.js"></script>
    <script src="js/jquery.tablesorter.widgets.min.js"></script>
</body>
</html>

我的JavaScript，将显示一个表格。但是我想使用Tablesort插件向表中添加排序功能，因此我在表标签中添加了class =“ tablesorter”。但表排序器不起作用...

var product=[];
var quantity=[];
var date=[];
var grossprice=[];
var profit=[];
var divText=[];

function searchXML()
{

    if (window.XMLHttpRequest)
        {// code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp=new XMLHttpRequest();
        }
        else
        {// code for IE6, IE5
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
        }
    xmlhttp.open("GET","xml/test.xml",false);
    xmlhttp.send();
    xmlDoc=xmlhttp.responseXML;

    x=xmlDoc.getElementsByTagName("ProductName");
          input = document.getElementById("input").value;

              return false;
          }

如何解决这个问题？谢谢

最佳答案

divText="<h2>The product details are:</h2><br /><table border=1 class="tablesorter">";

应该：

divText="<h2>The product details are:</h2><br /><table border=1 class=\"tablesorter\">";

您要追加divText，并且已将tablesorter（）应用于divText2。通过以下方式更改代码：

在最终其他条件之后，删除document.getElementById("results").innerHTML= divText;
粘贴此代码：-

var divText2 = $(divText);divText2.tablesorter();$("#results").append(divText2);
