我正在尝试在表单文本输入中键入url,而在onBlur上,使用url中指定的网页更新包含的iframe的内容。我似乎无法让它工作,我无法弄清楚为什么...... :)
有人可以帮助我吗?
这是代码......

function setIframeSource() {
var theSelect = document.getElementById('location');
var theIframe = document.getElementById('myIframe');
var theUrl;
theUrl = document.getElementById("location");
theIframe.src = theUrl;
}
// end hide -->
</script>

<body><center>
<form id="form1" method="post">
<input type="text" style="width:150px;" name="location2" id="location" onBlur="setIframeSource();">
</form>
<table width="100%" height="100%" border="1">
<tr>
<td width="300"><iframe src="http://www.ibm.com" id="myIframe" width="280" height="300" name="frame1"></iframe></td>
</tr>
</table>
</center>
</body>
</html>

function setIframeSource() {
var theSelect = document.getElementById('location');
var theIframe = document.getElementById('myIframe');
var theUrl;
theUrl = document.getElementById("location");
theIframe.src = theUrl;
}
也许问题在于上面的第5行 - 它应该是:
theUrl = document.getElementById("location").value;
目前,您将输入元素本身分配给theUrl
,这不是theIframe.src
的有效值!

尝试在设置iframe
的{{1}}:
src
并从输入中获取值:
theIframe.contentDocument.location.reload(true);
