在<a> tag

Question

I would like to split the below value:

var stringValue = "<a href="/DE/Company/OurOrganisation/ActionsDE.pdf">DE</a><a href="/EN/Company/OurOrganisation/Act‌​ionsEN.pdf">EN</a><a href="/FR/Company/OurOrganisation/Act‌​ionsFR.pdf">FR</a>";

As we see, there are 3 anchors hence I have tried

1. var result = stringValue.split("<a/>");

2. var myRegexp = new RegExp("<a/>");
   var result = stringValue.split(myRegexp);

What would be the best regex or way to get these 3 anchors ?

Answer 1

这是一个纯正的正则表达式解决方案：

＆＃13;

＆＃13;

var stringValue = '<a href="/DE/Company/OurOrganisation/ActionsDE.pdf">DE</a><a href="/EN/Company/OurOrganisation/Act‌ionsEN.pdf">EN</a><a href="/FR/Company/OurOrganisation/Act‌ionsFR.pdf">FR</a>';

var ar = stringValue.match(/<a.*?<\/a>/g)

console.log(ar)

＆＃13;

＆＃13;

＆＃13;

Answer 2

您可以使用正向预测断言来获得分割位置

var stringValue = '<a href="/DE/Company/OurOrganisation/ActionsDE.pdf">DE</a><a href="/EN/Company/OurOrganisation/Act‌​ionsEN.pdf">EN</a><a href="/FR/Company/OurOrganisation/Act‌​ionsFR.pdf">FR</a>';

var res = stringValue.split(/(?=<a.*?<\/a>)/);

console.log(res);

Answer 3

你已经在那里，只需要一个额外的步骤（好吧，可能是2）

var finalArray = stringValue.split("</a>").filter( function(val){
  return val.length > 0; //filter out empty results
}).map( function(val){
  return val + "</a>"; //append "</a>" to the rest of the results
})

Answer 4

首先，您的字符串包含双引号（"），您应该将它们转义或将其封装在单引号（'）中。

var stringValue = '<a href="/DE/Company/OurOrganisation/ActionsDE.pdf">DE</a><a href="/EN/Company/OurOrganisation/Act‌​ionsEN.pdf">EN</a><a href="/FR/Company/OurOrganisation/Act‌​ionsFR.pdf">FR</a>';

var result = stringValue.split("</a>")
             .filter(function(item) { 
                  return item ? true : false; 
              })
              .map(function(item) { 
                  return item + '</a>';
              });
