How can I extract two strings from a string with javascript?

Question

I have a string that contains the following:

<form class="form" 
data-action="Create" 
data-entity="Topic" 
data-href="/Admin/Contents/JsonCreate" 
data-rowkey="007H" 
data-partitionkey="0006000" id="form">

How can I get the values of data-rowkey and data-partitionkey from this string and put into javascript variables?

Please note my data is not part of a page. This is still data in a string.

Answer 1

let formstring是包含表单声明的字符串：

formstring.match(/data-rowkey=.+?"/i)[0].split('=')[1].replace(/"/g,'');

Answer 2

如果你使用jquery，你总是可以去

var data = $('.form').attr('data-rowkey);

Answer 3

$("#form").attr("data-rowkey") 

Answer 4

var str = '<form class="form" data-action="Create" 
data-entity="Topic" data-href="/Admin/Contents/JsonCreate" 
data-rowkey="007H" data-partitionkey="0006000" id="form">';

var rowkey = str.match(/data-rowkey=(.+) data-partitionkey=(.+)/)[1];
var partition =str.match(/data-rowkey=(.+) data-partitionkey=(.+) id="form"/)[2];
