鉴于以下html源代码是一个字符串，我将如何解析它以提取var dataObject并将其作为具有属性的对象返回给用户？

目前我正在使用以下技术方法，该方法并不总是以正确的格式返回字符串：
function getProductName(html) {
var temp = document.createElement('div');
temp.innerHTML = html;
var name = temp.querySelector('h1[itemprop*=\'name\']').textContent.trim();
$log.debug('Name found: ' + name);
return name;
}
答案 0 :(得分：1)
您可以在以下示例中完成：
var givenString = "<script>var dataObject={firstname: 'rahul'}</script>"
var doc = new DOMParser().parseFromString(givenString, 'text/html');
var scriptContent = doc.getElementsByTagName('script');
var dataObject = [].map.call(scriptContent, function(item) {
return item.textContent;
});
//try this code to get the real object
var a = dataObject[0];
a += ';return dataObject;'; //dataObject is the name of the variable that contains what I want to return
var f = new Function(a);
console.log(f);
var object = f();
console.log(object); //will give you the object
