jQuery以字符串格式在标记内部抓取文本并添加到数组

问题描述

我有字符串就像

 Lorem Ipsum is simply dummy text of the printing and typesetting
 industry.<grab> First Item</grab>Lorem Ipsum is simply dummy text of
 the printing and typesetting industry.<grab>Second Item</grab>Lorem
 Ipsum is simply dummy text of the printing and typesetting
 industry.<grab>Third Item</grab>Lorem Ipsum is simply dummy text of
 the printing and typesetting industry.

现在我需要获取< grab>之间的所有文字。 ..< / grab> 标记并添加两个数组。我尝试了这个，但它没有通过

now I need to grab all text between the <grab>....</grab> tags and add them two an array. I tried this but it didnt go through

var data = 'Lorem Ipsum is simply dummy text of the printing and typesetting industry.<grab> First Item</grab>Lorem Ipsum is simply dummy text of the printing and typesetting industry.<grab>Second Item</grab>Lorem Ipsum is simply dummy text of the printing and typesetting industry.<grab>Third Item</grab>Lorem Ipsum is simply dummy text of the printing and typesetting industry.';

var array = $('<grab>').map(function() {
  return $(this).text();
}).get();
$('body').append(array);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

你能告诉我怎么做吗

推荐答案

实际上这些不是DOM元素，因此可能正则表达式会帮助你。

Those are not DOM elements actually, so probably regex would help you.

var data = 'Lorem Ipsum is simply dummy text of the printing and typesetting industry.<grab> First Item</grab>Lorem Ipsum is simply dummy text of the printing and typesetting industry.<grab>Second Item</grab>Lorem Ipsum is simply dummy text of the printing and typesetting industry.<grab>Third Item</grab>Lorem Ipsum is simply dummy text of the printing and typesetting industry.';
var r = /<grab>(.*?)<\/grab>/g;
var grabs = data.match(r).map(function(x){
   return x.replace(r,'$1');
});
console.log(grabs);
