Javascript 解析HTML响应主体字符串以提取部分

我通过Ajax get请求接收到一个响应主体，在该主体中，我感兴趣的是一个特定部分，如下所示：

if (w2.isHidden() == false) {
    var counterValue = 0;
    try {
        var url = site + '/user.widget?page=just_data&query=Select IFNULL( time(MAX(longestWaitingSeconds), "unixepoch") , time(0, "unixepoch")) From AvayaCMSAT_skill';
        var loader = dhtmlxAjax.getSync(url);
        var text = loader.xmlDoc.responseText;
        var dataCells = text.split("<cell>");
        if (dataCells.length >= 2) {
            counterValue = dataCells[1];
            counterValue = counterValue.substring(0, counterValue.indexOf("<"));
        }
    } catch (err) {}
    var elem = document.getElementById("counter2_Value");
    elem.innerHTML = counterValue;
}

if (w5.isHidden() == false) {
    var counterValue = 0;
    try {

    elem.innerHTML = counterValue;

如上所述，我感兴趣的是提取开头和结尾{}之间的字符串并将其放入数组中。我希望能够对原始响应体字符串中显示的所有if语句执行此操作

我已经了解了如何使用和indexOf（）/substring（），例如：

但我还没有设法在开始和结束的花括号之间找到字符串。

var tempWidgetContent=html.match（/w\d+\.ishiden（.*）\（\）==false\）[\s\s]*？catch\（err\）\{\}/gm）；
var tempWidgetContent = html.match(/w\d+\.isHidden(.*)\(\) == false\)[\s\S]*?catch\(err\)\{ \}/gm);

for (var i = 0; i < tempWidgetContent.length; i++) {
    var widgetContent = tempWidgetContent[i].substring(tempWidgetContent[i].indexOf('{') + 1);
}

对于（var i=0；i

---

这就成功了。

您是否可以用它创建一个

链接，以便尝试修复。@anubhava嗨，我刚刚解决了这个问题，我很快就会发布解决方案。我使用字符串匹配和子字符串不是最传统的方法，但正在满足我的需要。非常感谢您的兴趣。好的，让我看看。这是链接。对不起，忽略上面的链接。很抱歉。对不起，我不太了解手机上的用户界面编码。

var start = html.indexOf("false) {", 0) + 8;
var end = html.indexOf("if (w", start);
alert(html.substring(start, end));

var tempWidgetContent = html.match(/w\d+\.isHidden(.*)\(\) == false\)[\s\S]*?catch\(err\)\{ \}/gm);

for (var i = 0; i < tempWidgetContent.length; i++) {
    var widgetContent = tempWidgetContent[i].substring(tempWidgetContent[i].indexOf('{') + 1);
}
