How to decode URI string using javascript?

Question

So I'm trying to decode this string %21%22%23%C2%A4%25%26%2F to !"#¤%&/ inside my confirm so it doesn't say the encoded string in the confirm, but the actual string. But how can I do this?

I tried something like this, but it doesn't work.

...
if(confirm('Are you sure you want to removed the JQL: ' + decodeStr(encoded_string_value))){
...
}
function decodeStr(strVal) {
 var decodeStr = '';
 if(strVal && typeof strVal === 'string') {
 // strip script/html tags
 decodeStr = strVal.replace(/<script[^>]*>([\S\s]*?)<\/script>/gmi, '');
 decodeStr = decodeStr.replace(/<\/?\w(?:[^"'>]|"[^"]*"|'[^']*')*>/gmi, '');
 return decodeStr;
 }
}

Is there another way of doing this?

• Hardik Shah: What is your actual string? or encoded string? Sample will help

Answer 1

Did you try?

decodeURI(strVal)

or

decodeURIComponent(strVal)

• Carsten Massmann: You will need to use decodeURIComponent("%21%22%23%C2%A4%25%26%2F") // '!"#¤%&/'to get the wanted result.
• Alexander: @CarstenMassmann Good call
• Mads Sander Høgstrup: Thanks! had only tried decodeURI... decodeURIComponent works!
