如果你注意到上面的字符串中有一个重复的模式总是从以下开始：
if (w[number].isHidden() == false){
我对之后以及最后一个结束前的内容感兴趣。例如，在这种情况下：
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
}
如上所述，我有兴趣在开始和结束之间提取字符串并将其放入数组中。我希望能够为orignal响应正文字符串中显示的所有if语句执行此操作。
我已经看过使用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));
但是我没有设法在开括号和大括号之间得到字符串。
答案 0 :(得分：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);
}
这就是诀窍。
