php – Use JavaScript to stripslashes ? possible

Posted by: admin July 12, 2020 Leave a comment

Questions:

I’m using ajax to grab a URL. The problem is the URL has slashes in it and when the JQuery load takes place afterwords it will not load the page.

AJAX success bit:

success: function(data) {
 $('#OPTcontentpanel').load(data.OPTpermalink);

PHP

echo json_encode( array('OPTpermalink'=>$OPTpermalink,));

AND the response

http:\/\/www.divethegap.com\/update\/options\/padi-open-water\/

So need to strip the slashes. I know how to do it in PHP but not in AJAX JavaScript.

Any ideas?

Marvellous

How to&Answers:

A new answer to an old question:

String.prototype.stripSlashes = function(){
    return this.replace(/\(.)/mg, "$1");
}

Example of use:

var str = "You\'re slashed \/\..\/\"; // Text from server
str = str.stripSlashes() ;

output:

You're slashed /\../\

Answer:

There has been a good port of many of php’s core functions, including stripslashes over here: http://phpjs.org/functions/stripslashes/

function stripslashes (str) {

  return (str + '').replace(/\(.?)/g, function (s, n1) {
    switch (n1) {
    case '\':
      return '\';
    case '0':
      return '\u0000';
    case '':
      return '';
    default:
      return n1;
    }
  });
}

Answer:

This is an old post but thought I would add my answer, seems more efficient than some other answers here:

var url = "http:\/\/www.divethegap.com\/update\/options\/padi-open-water\/"

var res = url.replace(new RegExp("\\", "g"), "");

This will replace all occurrences of a backslash character with nothing.

Answer:

You’re sending JSON, but inserting it directly into a HTML element. That is not wise, can create broken results, and probably not what you want to do in the first place.

You should probably either

  • change the PHP script’s output to create proper HTML

  • expect JSON on the JavaScript side (using jQuery’s dataType parameter, or the shorthand $.json(), and parse that

Answer:

Have you tried string.replace?

success: function(data) {
 $('#OPTcontentpanel').load(data.OPTpermalink.replace("\", ""));
