我有一个运行在javascript 1.7.1上的网站，每当我点击一个运行Javascript方法的按钮时，网页加载变得更加沉重，并且持续运行javascript直到网站开始滞后。这里是我的JS方法的一个例子：
function makeGraph() {
var cityValue = [];
var cityValue2 = [];
var cityName = [];
var numIndex = [];
var tDelivery = [];
var tIdle = [];
var tRepair = [];
var tReady = [];
var barColor = "";
var cityString = "";
var chrt = document.getElementById("myCanvas");
var cityList = [];
cityList = arguments;
$.ajax({
url: '../api/values',
type: 'GET',
datatype: 'json',
success: function (data) {
for (var j = 1; j < cityList.length; j++)
{
cityString = cityString + "||" + " data[i].Names==\"" + cityList[j] + "\"";
}
cityString = "data[i].Names==\"" + cityList[0] + "\""+cityString;
for (var i = 0; i < data.length; i++) {
if (eval(cityString)) {
numIndex.push(i);
}
}
for (var k = 0; k < numIndex.length; k++) {
cityValue.push(data[numIndex[k]].ValuesDouble);
cityValue2.push(data[numIndex[k]].ValuesDouble2);
cityName.push(data[numIndex[k]].Names);
tDelivery.push(data[numIndex[k]].truckDelivery);
tIdle.push(data[numIndex[k]].truckIdle);
tRepair.push(data[numIndex[k]].truckRepair);
tReady.push(data[numIndex[k]].truckReady);
}
if (numIndex.length > 0) {
for (var h = 0; h < numIndex.length - 1; h++) {
barColor = barColor + "{y:" + cityValue2[h] + ",color:'" + setGraphColor(cityValue2[h], cityValue[h]) + "'}" + ",";
}
barColor = "[" + barColor + "{y:" + cityValue2[numIndex.length-1] + ",color:'" + setGraphColor(cityValue2[numIndex.length-1],cityValue[numIndex.length-1]) + "'}" + "]";
}
else {
barColor = "[" + barColor + "{y:" + data[numIndex[0]].ValuesDouble2 + ",color:'" + setGraphColor(data[numIndex[0]].ValuesDouble2, data[numIndex[0]].ValuesDouble) + "'}" + "]";
}

我还在IE 11中运行了一个开发人员工具，它向我展示它确实来自不间断的javascript循环。我想知道是否有人可以帮助我停止JS循环以使其不连续。（我也使用SignalR，我不知道这是否是其中一个因素。）谢谢。

是的，我在这个函数中使用了highchart.js，按钮是这样的，所以我可以根据我点击的按钮刷新和排序图形，在这些情况下是城市的类别。
