According to this questionthe maximum practical length of a URL is 2000 characters. This isn't going to be able to hold a massive Wikipedia article like you're trying to send.
根据这个问题，一个 URL 的最大实际长度是 2000 个字符。这将无法像您尝试发送的那样容纳大量的维基百科文章。
Instead of putting the data on the URL you should be putting it in the body of a POST request. You need to add a datavalue to the object you're passing to the ajax function call. Like this:
您应该将数据放在 POST 请求的正文中，而不是将数据放在 URL 上。您需要向data传递给 ajax 函数调用的对象添加一个值。像这样：
function editAbout(){
var about=escape( $("#editorAbout").text());
$.ajax({
url: "Allcammand.aspx?cmd=EditAboutCompany&idCompany="+getParam("idCompany"),
type:"post",
async: false,
data: {
about: about
},
success: function(response){
},
error:function(xhr, ajaxOptions, thrownError){alert(xhr.responseText); ShowMessage("??? ?? ?????? ??????? ????","fail");}
});
}

In my case, there was a run-time error just before the post call. Fixing it resolved the problem.
就我而言，在 post 调用之前有一个运行时错误。修复它解决了问题。
The run-time error was trying to read $('#example').val()where $('#example')element does not exist (i.e. undefined).
运行时错误是试图读取$('#example').val()其中$('#example')的元素不存在（即undefined）。
I'm sure this will, certainly, help someone.
我相信这肯定会帮助某人。

In my case, the error was raised even though I was using 'POST' and the call to the server was successful. It turned to be that I was missing the dataType attribute...strange but now it works
就我而言，即使我使用的是“POST”并且对服务器的调用成功，也会引发错误。原来是我缺少 dataType 属性......奇怪，但现在它可以工作了
return $.ajax({
url: url,
type: 'POST',
dataType: 'json',
data: JSON.stringify(data)
})
