保留div的内容

我有一个 div，其内容名为 level0 (

)。不幸的是，我的网页中的 level0 发生了变化，我需要重用具有相同第一个值的 div 。

我怎样才能实现这个目标？

我的代码：

<body onload ="init()">
          <h1>Search engine bêta version</h1>
      <input id="text" type="text" size="60" value="Type your keywords" />
      <input type="button" value="Display the results" onclick="check();" />

      <script ="text/javascript">

      function check() {
          var div = document.getElementById("level0");   // Here level0 takes the value of Type your keywords and I want it to stick with the first value
          div.innerHTML = document.getElementById("text").value;
      }

     </script>

      <div id="level0"> // The value I want to keep
      </div>

</body>

I've got a div which has a content named level0 (<div id="level0">). Unfortunately level0 changes in my webpage and I need the reuse the div with the same first value.

How can I achieve this?

Edit

My code:

<body onload ="init()">
          <h1>Search engine bêta version</h1>
      <input id="text" type="text" size="60" value="Type your keywords" />
      <input type="button" value="Display the results" onclick="check();" />

      <script ="text/javascript">

      function check() {
          var div = document.getElementById("level0");   // Here level0 takes the value of Type your keywords and I want it to stick with the first value
          div.innerHTML = document.getElementById("text").value;
      }

     </script>

      <div id="level0"> // The value I want to keep
      </div>

</body>

如果想使用您显示结果的第一个“文本”，此代码可能有用

搜索引擎测试版

  <script ="text/javascript">
var i=1;
var firstText;
  function check() {
  if(i==1)
  {
    firstText=document.getElementById("text").value;
  }
      var div = document.getElementById("level0");   // Here level0 takes the value of Type your keywords and I want it to stick with the first value
      div.innerHTML = document.getElementById("text").value;
      i++;
      alert(firstText);
  }

 </script>

  <div id="level0"> // The value I want to keep
  </div>

If want to use the first "text" for which you had displayed results this code may be useful

Search engine bêta version

  <script ="text/javascript">
var i=1;
var firstText;
  function check() {
  if(i==1)
  {
    firstText=document.getElementById("text").value;
  }
      var div = document.getElementById("level0");   // Here level0 takes the value of Type your keywords and I want it to stick with the first value
      div.innerHTML = document.getElementById("text").value;
      i++;
      alert(firstText);
  }

 </script>

  <div id="level0"> // The value I want to keep
  </div>

下面的代码应该可以为您解决这个问题。第一次替换时，它会存储原始内容，然后每次更改 div 中的文本时，都会在其前面添加原始内容。

<body onload ="init()">
      <h1>Search engine bêta version</h1>
      <input id="text" type="text" size="60" value="Type your keywords" />
      <input type="button" value="Display the results" onclick="check();" />

      <script ="text/javascript">
      //Whether or not we're replacing the content in the div for the first time
      var firstReplace = true;
      //The original content of the div
      var originalContent;
      function check() {
        var div = document.getElementById("level0");   // Here level0 takes the value of Type your keywords and I want it to stick with the first value
        //Check if this is the first time
        if (firstReplace) {
            //Is the first time, so store the content
            originalContent = div.innerHTML;
            //Set firstReplace to false, so we don't overwrite the origianlContent variable again
            firstReplace = false;
        }
        div.innerHTML = originalContent + ' ' + document.getElementById("text").value;
      }
     </script>

      <div id="level0"> // The value I want to keep
      </div>

</body>

The code below should solve this for you. On the first time it replaces, it will store the original content, and then each time it changes the text in the div, it will prepend it with the original content.

<body onload ="init()">
      <h1>Search engine bêta version</h1>
      <input id="text" type="text" size="60" value="Type your keywords" />
      <input type="button" value="Display the results" onclick="check();" />

      <script ="text/javascript">
      //Whether or not we're replacing the content in the div for the first time
      var firstReplace = true;
      //The original content of the div
      var originalContent;
      function check() {
        var div = document.getElementById("level0");   // Here level0 takes the value of Type your keywords and I want it to stick with the first value
        //Check if this is the first time
        if (firstReplace) {
            //Is the first time, so store the content
            originalContent = div.innerHTML;
            //Set firstReplace to false, so we don't overwrite the origianlContent variable again
            firstReplace = false;
        }
        div.innerHTML = originalContent + ' ' + document.getElementById("text").value;
      }
     </script>

      <div id="level0"> // The value I want to keep
      </div>

</body>
