iframe自动适应高度1 js:
function iFrameHeight() {var ifm= document.getElementById("iframepage");var subWeb =document.frames ? document.frames["iframepage"].document : ifm.contentDocument;if(ifm != null && subWeb != null) {ifm.height = subWeb.body.scrollHeight;}}
iframe:
<iframe id="iframepage" src="study_1.asp" frameborder="0" scrolling="no" style="width:100%; " onLoad="iFrameHeight()"></iframe>
下面的兼容性比较好：/*兼容FF/IE9/IE8/IE7/IE6*/function iframeResize(iframe) { try { //var iframe = document.getElementById("contentFrame"); //("contentFrame"); var idocumentElement = iframe.contentWindow.document.documentElement; if (idocumentElement.scrollHeight > 560) { iframe.height -= 5; iframe.height = idocumentElement.scrollHeight; } else { iframe.height = 560; } } catch (e) { window.status = 'Error: ' + e.number + '; ' + e.description; } }
iframe:
<iframe id="iframepage" src="study_1.asp" frameborder="0" scrolling="no" style="width:100%; " onLoad="iframeResize(this)"></iframe>
