javascript - 使用javascript从字符串html中读取span标签值

Question

我想获取来自 HTML 字符串的 span 值。示例代码链接-http://jsfiddle.net/9cCHy/58/

 var mystring = '<div class="table-cell"> <span>test</span>            </div> <span id="isbool" style="display:none">True</span></div>';

    var after = $('<div/>').html(mystring).find("span[id='isbool']").contents().unwrap().end().end().html();
    // want to capture value true without any dependency of html
    alert(after);

.text()方法可以给你目标元素的文本内容:

var mystring = '<div class="table-cell"> <span>test</span>            </div> <span id="isbool" style="display:none">True</span></div>';

var after = $('<div/>').html(mystring).find("span[id='isbool']").text();
// want to capture value true without any dependency of html
console.log(after);
