我把绳子扭了错误.响应文本从这个 answer .

var element = $(error.responseText);

元素是这样的

标题在位置2的红色框中,索引为1。我能找到它(

 elem.get(1).innerHTML
 elem.get(1).text
 element[1].innerHTML
 element[1].text

但是我想通过Jquery以下面的方式找到这个值。因为在将来的某些情况下,我可能需要按属性名而不是索引值来搜索对象中的元素。如果可能的话,请帮助我。

$("title", element).html()
$(element).find("title").html()

你可以用 $.parseHTML 将html字符串转换为DOM节点数组。它可以与jquery选择器和函数一起使用:

 var dom_nodes = $($.parseHTML(e.responseText));
 alert( dom_nodes.filter('title').text());

How to create Document objects with JavaScript

var doc = (new DOMParser).parseFromString(error.responseText, "text/html");
// first argument: html to be converted to doc
// second argument: mime_type (text/html or text/xml, it depends)

第二,你知道规矩。

doc.querySelector("title").textContent;
// $(doc).find("title").html();
// The resource cannot be found.

或者,使用$.parseHTML和filter节点。

var doc = $.parseHTML(error.responseText);
var titleNode = doc.filter(function (node) {
    return node.localName === "title";
});
console.log(titleNode[0].textContent);
