URL encode sees ampersand as amp HTML entity

Question

I am encoding a string that will be passed in a URL  via GET   But if I use escape  encodeURI or encodeURIComponent   amp  will be replaced with  26amp 3B  but I want it to be replaced with  26  What am I doing wrong

There is HTML and URI encodings   amp amp  is  amp  encoded in HTML while  26 is  amp  in URI encoding      So before URI encoding your string you might want to HTML decode and then URI encode it     var div   document createElement  div    div innerHTML     amp amp AndOtherHTMLEncodedStuff   var htmlDecoded   div firstChild nodeValue  var urlEncoded   encodeURIComponent htmlDecoded     result  26AndOtherHTMLEncodedStuff  Hope this saves you some time

If you did literally this   encodeURIComponent   amp      Then the result is  26  you can test it here   Make sure the string you are encoding is just  amp  and not  amp amp  to begin with   otherwise it is encoding correctly  which is likely the case   If you need a different result for some reason  you can do a  replace   amp amp  g   amp    before the encoding

Without seeing your code  it s hard to answer other than a stab in the dark   I would guess that the string you re passing to encodeURIComponent    which is the correct method to use  is coming from the result of accessing the innerHTML property   The solution is to get the innerText textContent property value instead   var str       el   document getElementById  myUrl     if   textContent  in el      str   encodeURIComponent el textContent   else     str   encodeURIComponent el innerText     If that isn t the case  you can use the replace   method to replace the HTML entity   encodeURIComponent str replace   amp amp  g    amp
