How to convert string into jquery object

This time I will explain in detail how to convert a string into a jquery object, and what are the precautions for converting a string into a jquery object. The following is a practical case, let's take a look.

jQuery(test)[0].outerHTMLouterHTML
是部分浏览器提供的原生DOM属性，可返回包括元素本身在内的html代码。
如果不需要标签本身，可用jQuery的html方法来获取html文本
jQuery(test).html()
var test=&#39;<p>.<img src="oldsrc" />.</p>&#39;
var jObj=$(test);
var imgs=jObj.find(&#39;img&#39;);
imgs.each(function(){
  $(this).attr(&#39;src&#39;,&#39;newsrc&#39;);
  });
test=jObj[0].outerHTML;
或者
test=&#39;<p>&#39;+jObj.html()+&#39;</p>&#39;;
这里只能用DOM片断来做，无法带上html

Or you can directly use regular expressions to replace

&#39;<p><img src="oldsrc" /></p>&#39;.replace(
/<img(\s+[^>]*)src="([^"]+)"([^>]*)>/ig,
function(a,b,c,d){    //这里a代码匹配到的一个img元素的整个字符串,b代码第一个括号内的内容，c代码第二个括号的内容，就是img的src,d代码后面的内容
//这里可以处理下c再连接，也可以直接写新的src
return &#39;<img&#39;+b+&#39;src="&#39;+&#39;new src&#39;+&#39;"&#39;+d+&#39;>&#39;;
})

or like this:

var a=&#39;<p>123</p>&#39;;
var jObj=$(a);
console.log($(&#39;<input></input>&#39;))
