javascript正则表达式替换标签中的“”

Question

I got a string like this :

"{"name":"joy","tag":"<img src="/1/1.png"/>hello<img src="/1/2.png">"}"

I know how to match all chars between <> , but have no idea how to replace certain char ... I want to replace " with ' .

Answer 1

you can do something like

 var result = "{\\"name\\":\\"joy\\",\\"tag\\":\\"<img src=\\"/1/1.png\\"/>hello<img src=\\"/1/2.png\\">\\"}".replace(/<(.*?)>/g, function(a, b){ return a.replace(/"/g, "'"); }); console.log(result); 

and this will replace all the quotes inside the html elements for single quotes, the 'g' is to replace ALL the occurrences

Hope it helps.

Answer 2

str = '{"name":"joy","tag":"<img src="/1/1.png"/>hello<img src="/1/2.png">"}';

Solution 1 :

res = str.match(/\<[^>]+\>/g);
for(var i = 0, l = res.length; i < l; i++){
    str = str.replace(res[i], res[i].replace(/"/g, "'"));
}

Solution 2 :
!!! This solution would be work only for one set of "" !!!

res = str.replace(/(\<[^">]*)"([^">]*)"([^>]*\>)/g, "$1'$2'$3");

Result :

"{"name":"joy","tag":"<img src='/1/1.png'/>hello<img src='/1/2.png'>"}"
