Jquery在添加加载额外内容的脚本后停止工作

Jquery stopped working after adding script which loads additional content

本文关键字：脚本 停止工作 额外内容 添加 加载 Jquery      更新时间：2023-09-26

我有一个问题与jquery。我在我的网站上添加了一个脚本，可以加载额外的内容到页面。

问题是，在同一页面上，我也有一个javascript绑定复选框-它停止工作，因为read()函数。以前的解决方案，我收到这里没有工作(或我不能使它工作)，所以我决定做一个简短的例子(绑定脚本是在最后):

<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
    <title>Ajax Rotating Includes Script</title>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
    <script type="text/javascript">
      var loadedobjects = ""
      var rootdomain = "http://" + window.location.hostname
        function ajaxpage(url, containerid) {
          var page_request = false
          if (window.XMLHttpRequest) // if Mozilla, Safari etc
            page_request = new XMLHttpRequest()
          else if (window.ActiveXObject) { // if IE
            try {
              page_request = new ActiveXObject("Msxml2.XMLHTTP")
            } catch (e) {
              try {
                page_request = new ActiveXObject("Microsoft.XMLHTTP")
              } catch (e) {}
            }
          } else return false
          page_request.onreadystatechange = function () {
            loadpage(page_request, containerid)
          }
          page_request.open('GET', url, true)
          page_request.send(null)
        }
        function loadpage(page_request, containerid) {
          if (page_request.readyState == 4 && (page_request.status == 200 || window.location.href.indexOf("http") == -1)) document.getElementById(containerid).innerHTML = page_request.responseText
        }
        function loadobjs() {
          if (!document.getElementById) return
          for (i = 0; i < arguments.length; i++) {
            var file = arguments[i]
            var fileref = ""
            if (loadedobjects.indexOf(file) == -1) { //Check to see if this object has not already been         added to page before proceeding
              if (file.indexOf(".js") != -1) { //If object is a js file
                fileref = document.createElement('script')
                fileref.setAttribute("type", "text/javascript");
                fileref.setAttribute("src", file);
              } else if (file.indexOf(".css") != -1) { //If object is a css file
                fileref = document.createElement("link")
                fileref.setAttribute("rel", "stylesheet");
                fileref.setAttribute("type", "text/css");
                fileref.setAttribute("href", file);
              }
            }
            if (fileref != "") {
              document.getElementsByTagName("head").item(0).appendChild(fileref)
              loadedobjects += file + " " //Remember this object as being already added to page
            }
          }
        }
    </script>
  </head>
  <body>    
    <div id="leftcolumn">
      <a href="javascript:ajaxpage('ajaxfiles/external.htm', 'rightcolumn');">Porsche Page</a>
      <a href="javascript:ajaxpage('ajaxfiles/external2.htm', 'rightcolumn');">Ferrari Page</a>
      <a href="javascript:ajaxpage('ajaxfiles/external3.htm', 'rightcolumn');">Aston Martin Page</a>
      <div style="margin-top: 2em">Load CSS & JS files</div>
      <a href="javascript:loadobjs('ajaxfiles/style.css', 'ajaxfiles/tooltip.js');">Load "style.css" and "tooltip.js"</a>    
    </div>    
    <div id="rightcolumn" class="qqryq"><h3>Choose a page to load.</h3></div>
    <div style="clear: left; margin-bottom: 1em"></div>
    <form>
      <input type="checkbox" name="qqryq" class="master" value="1">Wódz<BR>
      <div class="test">
        --<input type="checkbox" name="qqryq" class="slave" value="1"><BR>
        --<input type="checkbox" name="qqryq" class="slave" value="1"><BR>
        --<input type="checkbox" name="qqryq" class="slave" value="1"><BR>
        --<input type="checkbox" name="qqryq" class="slave" value="1"><BR>
      </div>
    </form>
  <script>
    $(document).ready(function () {
      $(".slave").click(function () {
        if (this.checked == true) {
          $(".master").attr('checked', this.checked);
        }
      });
    });
  </script>

最后是我在添加ajax内容加载之前使用的脚本。然后我被告知要这样修改:

<script>
  $(document).ready(function () {
    $(".test").on('change', '.slave', function () {
      if (this.checked) $(".master").attr('checked', this.checked);
    });
  });
</script>

我该怎么做才能使它工作?

看起来你有一个流浪的* /在你的第一个大<script>块的末尾，它导致语法错误。删除它应该可以解决您的问题。

该代码块的末尾(第57行左右)当前为:

        if (fileref != "") {
          document.getElementsByTagName("head").item(0).appendChild(fileref)
          loadedobjects += file + " " //Remember this object as being already added to page
        }
      }
    } * /
</script>

应该是:

        if (fileref != "") {
          document.getElementsByTagName("head").item(0).appendChild(fileref)
          loadedobjects += file + " " //Remember this object as being already added to page
        }
      }
    }
</script>
