iframe 页面自适应长宽

脚本:

View Code
// 调用 IFrameReSize("mainFrame");IFrameReSizeWidth("mainFrame");
//iframe高度自适应
  function IFrameReSize(iframename) {
         var pTar = document.getElementById(iframename);
      if (pTar) {  //ff
          if (pTar.contentDocument && pTar.contentDocument.body.offsetHeight) {
              pTar.height = pTar.contentDocument.body.offsetHeight;
          } //ie
          else if (pTar.Document && pTar.Document.body.scrollHeight) {
              pTar.height = pTar.Document.body.scrollHeight;
          }
      }
  }

  //iframe宽度自适应
  function IFrameReSizeWidth(iframename) {
      var pTar = document.getElementById(iframename);
    
      if (pTar) {  //ff
          if (pTar.contentDocument && pTar.contentDocument.body.offsetWidth) {
              pTar.width = pTar.contentDocument.body.offsetWidth;
          }  //ie
          else if (pTar.Document && pTar.Document.body.scrollWidth) {
              pTar.width = pTar.Document.body.scrollWidth;
          }
      }
  }

页面调用:

View Code
<iframe name="paymentIframe" id="paymentIframe" onload='IFrameReSize("paymentIframe");IFrameReSizeWidth("paymentIframe");'
        src="/docc/blank.jsp" align="center" allowtransparency="true" scrolling="auto" width="100%"  height="100%"
        frameborder="0" leftmargin="0" topmargin="0" marginwidth="0" marginheight="0" noresize></iframe>

 

在新增或修改iframe信息后的js中也需要重新设置IFrame的长宽。

IFrameReSize("paymentIframe");IFrameReSizeWidth("paymentIframe");
