Removing dollar signs from prices

rated 0 times [ 178] [ 4] / answers: 1 / hits: 36780 / 14 Years ago, wed, november 17, 2010, 12:00:00

I'm building a string of amounts but need to remove the dollar signs. I have this jQuery code:

  buildList($('.productPriceID > .productitemcell'), 'pricelist')

It's returning

pricelist=$15.00,$19.50,$29.50

I need to remove the dollar signs but can't seem to figure it out. Tried using .trim but I think that removes only white space.

Sorry for the newbie question! Thanks in advance for any help!

Here's the full code:

function buildList(items, name) {

var values = [];

items.each(function() {

values.push(this.value || $(this).text());

});

return name + '=' + values.join(',');

}



var result = [

buildList($('.productCodeID > .productitemcell'), 'skulist'),

buildList($('.productQuantityID > .productitemcell > input'), 'quantitylist'),

buildList($('.productPriceID > .productitemcell'), 'pricelist')

];



var string = result.join('&');

Here is the raw code before the javascript runs

<span class=productPriceID>

<div class=productitemcell>$15.00</div>

<div class=productitemcell>$19.50</div>

<div class=productitemcell>$29.50</div>

</span>

EDIT: Starting over with answer now that I have the code that is running.

Looking at your updated code, this should work:

Example: http://jsbin.com/ekege3/

var result = [

    buildList($('.productCodeID > .productitemcell'), 'skulist'),

    buildList($('.productQuantityID > .productitemcell > input'), 'quantitylist'),

    buildList($('.productPriceID > .productitemcell'), 'pricelist')

];



result[ 2 ] = result[ 2 ].replace(/$/g, '');



var string = result.join('&');

Side note: You can shorten your buildList function a little like this:

function buildList(items, name) {

    return (name + '=') + items.map(function() {

        return (this.value || $(this).text());

    }).get().join(',');

}

Original answer:

~~If you have a string, just use .replace().~~

var str = pricelist=$15.00,$19.50,$29.50; str = str.replace(/$/g, '');

Or are you saying that you have a variable pricelist containing an Array? If so, do this:

var pricelist = [$15.00,$19.50,$29.50]; for( var i = 0, len = pricelist.length; i < len; i++ ) { pricelist[ i ] = pricelist[ i ].replace('$', ''); }

EDIT: It sounds as though the buildList method returns an Array.

One way to check would be to do this:

alert( Object.prototype.toString.call( result[2] ) );

And see what it gives you.

Anyway, assuming it's an Array, here's the updated version of the second example.

var result = [ buildList($('.productCodeID > .productitemcell'), 'skulist'), buildList($('.productQuantityID > .productitemcell > input'), 'quantitylist'), buildList($('.productPriceID > .productitemcell'), 'pricelist') ]; // verify the data type alert( Object.prototype.toString.call( result[ 2 ] ) ); // loop over result[ 2 ], replacing the $ with '' for( var i = 0, len = result[ 2 ].length; i < len; i++ ) { result[ 2 ][ i ] = result[ 2 ][ i ].replace('$', ''); } var string = result.join('&');
