我不是最擅长 javascript，而且我遇到了一些麻烦。任何建议表示赞赏。
我试图在有人单击带有 onclick 事件的链接后生成图表。
我的文件的头部看起来像这样。
<script src="billajax.js" type="text/javascript"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script src="highcharts.js"></script>
<script src="exporting.js"></script>
Billajax.js 有很多功能，但为了简化，它看起来像这样。
function getl(uid){
if(document.getElementById("votescode")){
var xmlHttp = getXMLHttp();
xmlHttp.onreadystatechange = function()
{
if(xmlHttp.readyState == 4)
{
HandleResponse5(xmlHttp.responseText);
//BELOW GENERATES CHART CODE
var xmlHttp2 = getXMLHttp();
xmlHttp2.onreadystatechange = function()
{
if(xmlHttp2.readyState == 4)
{
HandleResponse4(xmlHttp2.responseText);
dothis();
}
}
xmlHttp2.open("GET", "ajax.php?&p=glv&req="+uid+"&n="+Math.random(), true);
xmlHttp2.send(null);
}
}
xmlHttp.open("GET", "ajax.php?&p=gl&req="+uid+"&n="+Math.random(), true);
xmlHttp.send(null);
}else{
var xmlHttp = getXMLHttp();
xmlHttp.onreadystatechange = function()
{
if(xmlHttp.readyState == 4)
{
HandleResponse5(xmlHttp.responseText);
//BELOW GENERATES CHART CODE
var xmlHttp2 = getXMLHttp();
xmlHttp2.onreadystatechange = function()
{
if(xmlHttp2.readyState == 4)
{
HandleResponse3(xmlHttp2.responseText);
dothis();
}
}
xmlHttp2.open("GET", "ajax.php?&p=glv&req="+uid+"&n="+Math.random(), true);
xmlHttp2.send(null);
}
}
xmlHttp.open("GET", "ajax.php?&p=gl&req="+uid+"&n="+Math.random(), true);
xmlHttp.send(null);
}
}
function HandleResponse3(response)
{
//var idid = 'waiting';
//toggle_visibility(idid);
var script = document.createElement("script");
script.setAttribute("id", "votescode");
script.innerHTML = response;
document.head.appendChild(script);
}
function HandleResponse4(response)
{
//var idid = 'waiting';
//toggle_visibility(idid);
var el = document.getElementById( 'votescode' );
el.parentNode.removeChild( el );
var script = document.createElement("script");
script.setAttribute("id", "votescode");
script.innerHTML = response;
document.head.appendChild(script);
}
function HandleResponse5(response)
{
//var idid = 'waiting';
//toggle_visibility(idid);
document.getElementById('initiative').innerHTML = response;
//var shn = $('.shtn').ThreeDots();
//shn.ThreeDots.update({max_rows:1});
//var bsy = $('.billsy').ThreeDots();
//bsy.ThreeDots.update({max_rows:3});
}
getL(uid)中ajax调用的输出如下，成功插入到文档头部。使用 HandleResponse5 填充的 html 内容也正确插入。
在我单击链接后，它会触发 getl(uid) 函数，该函数会生成插入页面所需的代码（highcharts 容器），然后它会使用 HandleResponse3 或 Handleresponse4 为 highcharts 生成代码，具体取决于之前是否触发了脚本。
生成高图的代码输出如下。如果我将它扔到 jsfiddle 中它会起作用，所以我无法弄清楚为什么我不断收到以下错误（来自 chrome 控制台）。
Uncaught TypeError: Object [object Object] has no method 'highcharts'
dothis

HandleResponse3 billajax.js:310
xmlHttp2.onreadystatechange billajax.js:247
Uncaught TypeError: Object [object Object] has no method 'highcharts'
dothis
xmlHttp2.onreadystatechange
这是调用 getl(uid) 中定义的 ajax.php 生成的代码
//CALL FROM BILL AJAX ABOVE WHICH GENERATES CODE BELOW.
xmlHttp2.open("GET", "ajax.php?&p=glv&req="+uid+"&n="+Math.random(), true);

我已经成功实现了一个类似的解决方案，但我无法弄清楚为什么当我使用类似的设置时它不能正常工作。
再次，任何建议将不胜感激。
