JavaScript正则表达式获取引号字符串中的单词

Question

Thanks for all, I met a problem in JavaScript, and the problem is:

I have a string: such as:

{"results":[{"id":"id1","text":"text1"},{"id":"id2","text":"text2"},{"id":"id3","text":"text3"}]}

Then, I want to get the string such as:

id1|text1|id2|text2|id3|text3

So how should I write the Regular Expression?

Thank you so much, and I am a new comer in StackOverFlow!

Answer 1

I have a string

That string is in JSON format , which works very well with JavaScript.

So how should I write the Regular Expression?

You should not write a regular expression at all. If you did, you only had two problems :

.replace(/(^.+?|"\\},\\{)?"id":"|","text":"|"}[^"]*$/g, "|").slice(1,-1)

Instead, parse the string into an object, and extract the id-text pairs from there:

var result = JSON.parse(string).results.map(function(el) {
    return el.id+"|"+el.text;
}).join("|");
