【问题描述】:
根据这个线程Can scripts be inserted with innerHTML? injecting some javascript in innerHTML 不应该工作。
那么为什么它在这种情况下有效:
<BR>
Below is the code injected with a div
</BR>
<div id="div_content">
</div>
<script>
function HttpRequest(url){
var pageRequest = false //variable to hold ajax object
/*@cc_on
@if (@_jscript_version >= 5)
try {
pageRequest = new ActiveXObject("Msxml2.XMLHTTP")
}
catch (e){
try {
pageRequest = new ActiveXObject("Microsoft.XMLHTTP")
}
catch (e2){
pageRequest = false
}
}
@end
@*/
if (!pageRequest && typeof XMLHttpRequest != 'undefined')
pageRequest = new XMLHttpRequest()
if (pageRequest){ //if pageRequest is not false
pageRequest.open('GET', url, false) //get page synchronously
pageRequest.send(null)
embedpage(pageRequest)
}
}
function embedpage(request){
//if viewing page offline or the document was successfully retrieved online (status code=2000)
if (window.location.href.indexOf("http")==-1 || request.status==200)
///document.write(request.responseText)
div_content.innerHTML = request.responseText;
}
HttpRequest("http://localhost/ajax/injecthtml/demo4/external.html") //include "external.html" onto current page
</script>
external.html
<img src="google.jpg" alt="" width="" height="" onclick="alert('Embedded Javascript within innerHTML works !!!')">
<br>
<img src="google.jpg" alt="" width="" height="" onclick="alert('Embedded Javascript within innerHTML works !!!')">

你确定吗?看到这个fiddle
-
@MoshFeu 是的,我很确定,因为我对其进行了测试并从测试中截取了屏幕截图。我使用纯 Javascript,而不是 jquery,它可以工作。
-
@MoshFeu 也许你的不起作用,因为你使用相对 URL,出于安全原因,它必须是绝对 URL,至少在 chrome 中。
