I am having trouble with some javascript. The code snippet below creates a simple post request however it always throws an NS_Error_failureexception (details at the bottom of the page). Can anyone tell me whats wrong with this code?
我在使用某些 javascript 时遇到问题。下面的代码片段创建了一个简单的发布请求，但它总是抛出NS_Error_failure异常（页面底部的详细信息）。谁能告诉我这段代码有什么问题？
window.onload = function () {
alert('0');
try {
var url = "Some URL";
var request = CreateHttpRequest();
if (request) {
alert('1');
request.open("POST", url, false);
request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
alert('2');
request.send('');
alert('3');
}
}
catch (err) {
alert(err);
}
}

I found the same problem and when I was sending all to an iframe, the problem solved when I add the "name" to the tag, maybe the target is not accesible by your script
我发现了同样的问题，当我将所有内容发送到 iframe 时，当我将“名称”添加到标签时问题解决了，也许目标无法被您的脚本访问
<iframe id="iframe_execute" name="iframe_execute" frameborder="1" height="400" width="400"></iframe>
