javascript - 解析 HTML 响应正文字符串以提取部分

Question

我通过 Ajax get 请求接收响应正文，在该正文中我对特定部分感兴趣，如下所示:

if (w2.isHidden() == false) {
    var counterValue = 0;
    try {

        var text = loader.xmlDoc.responseText;
        var dataCells = text.split("<cell>");
        if (dataCells.length >= 2) {
            counterValue = dataCells[1];
            counterValue = counterValue.substring(0, counterValue.indexOf("<"));

    elem.innerHTML = counterValue;

    }
    catch (err) {}
}

如果您注意到上面的字符串中有一个始终以以下内容开头的重复模式:

if (w[number].isHidden() == false){

我对最后一个括号之后和之前的内容感兴趣。例如在本例中:

if (w2.isHidden() == false) {

 //PART TO EXTRACT
      var counterValue = 0;
      try {
          var url = site + '/user.widget?page=just_data&query=Select IFNULL(time(MAX(longestWaitingSeconds), "unixepoch") , time(0, "unixepoch"))From vayaCMSAT_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;
     //END PART TO EXTRACT
 }

正如上面突出显示的，我感兴趣的是提取开始和结束 {} 之间的字符串并将其放入数组中。我希望能够对原始响应正文字符串中显示的所有 if 语句执行此操作。

我已经考虑过使用 regular expressions和indexOf()/substring()，例如:

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

但是我没有设法在左大括号和右大括号之间获取字符串。

Answer 1

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);
}

这成功了。
