javascript string replace < into <

Question

Hey all, I basically output content into a div like this using jquery:

var text = $("#edit").val();
$("#output").text(text);

But I want to turn "<" and ">" into "<" and ">".

text.replace(/</,"<"); doesn't seem to be working for me...

Any ideas? Many thanks

Are you sure the problem isn't somewhere else? If I type in chrome console "abcde<hey>dfdfgf".replace(/</g,"<").replace(/>/g,">") I get the correct answer... — 6502

Simple.

var needToConvert = 'But I want to turn "&lt;" and "&gt;" into "<" and ">".';

var convert = function(convert){
    return $("<span />", { html: convert }).text();
    //return document.createElement("span").innerText;
};

alert(convert(needToConvert));

@mdlars Could you be more specific? I just tried it, and it still works.

You could use something like the unescapeHTML() function in prototype...

Adapted from prototype js source

function unescapeHTML(escapedHTML) {
  return escapedHTML.replace(/&lt;/g,'<').replace(/&gt;/g,'>').replace(/&amp;/g,'&');
}

assign it to variable:

var text = $("#edit").val();
text = text.replace("&lt;","<");

this will work fine

This will only replace the first occurrence, others are ignored

You need use .html() Because text() converts all html tags

$("#output").html(text);
