jQuery, if contains X, do this, but conditional? -

i have line being populated database requires different formatting based on has been entered. there 3 types of formats:

line example 1) $3.00
line example 1) 2 per person $4.95
line example 2) small $5.00 | medium $10.00 | large $15.00

line 1) no changes required
line 2) need insert space before $
line 3) need insert space before , after | not before $ (all instances)

i've looked around , tried piece things can't quite it. here's have far:

      $('.menu-price-value:contains("$")').each(function() {          var newtext = $(this).html().replace('$', '<span class="space"></span>$');          $(this).html(newtext);        });          $('.menu-price-value:contains("|")').each(function() {          var newtext = $(this).html().replace("|", "&nbsp;|&nbsp;");          $(this).html(newtext);          $('.menu-price-value').addclass('remove-space');        });

there few problems

• javascript string replace replaces first match (bit lame know). use regex g (global) option replace occurances.
• you targetting matching classes in second example (not current match)

jsfiddle: http://jsfiddle.net/trueblueaussie/evn91m7y/1/

  $('.menu-price-value:contains(" $")').html(function () {       return $(this).html().replace(/\$/g, '<span class="space">                                             </span>$');   });    $('.menu-price-value:contains("|")').html(function () {       return $(this).html().replace(/\|/g, "&nbsp;|&nbsp;");   }).addclass('remove-space'); 

to avoid running $ check on | matches, can add :not(contains("|")) this:

  $('.menu-price-value:contains(" $"):not(:contains("|"))').html(function () {       return $(this).html().replace(/\$/g, '<span class="space">                                             </span>$');   });

or reverse check order , chain selectors .not() this: http://jsfiddle.net/trueblueaussie/evn91m7y/4/

notes:

• you can use function html(), replaced html returned value of each element.
• i differentiated between first example , others using fact other examples have space before $. alternative see of value starts with $ or not.
• i had add styling make space span visible.
• i exaggerated changes styling see them more easily.
