如何从包装成百分号的javascript变量中删除美元符号？

Question

I'm looking at a shopping cart that echos a variable when it is wrapped with two percentage signs.

For example, on an html page %%Amount%% would echo something like $4.50.

In javascript, I have something that reads:

var tag_params = {
prodid: '',
pagetype: 'cart',
totalvalue: '%%Amount%%',
};

The output for totalvalue contains a dollar sign, and I need to remove it.

How can I do this with the example above?

UPDATE:

I think that Ian and abc123 most likely gave the correct answer to this. In my particular case, it was not providing the output that I wanted to see in the source code, so I created a new global variable and removed the dollar sign in php then and there.

This echoed it the way I wanted when using %%ModifiedAmount%%.

Answer 1

You can call the replace function is JavaScript.

Original:

var tag_params = {
    prodid: '',
    pagetype: 'cart',
    totalvalue: '%%Amount%%'.replace('$', ''),
};

Updated to use lan 's method:

< script type = "text/javascript" >
    var tag_params = {
        prodid: '',
        pagetype: 'cart',
        totalvalue: '%%Amount%%',
    };

    tag_params.totalValue = tag_params.totalValue.replace('$', ''); 
< /script>

Answer 2

tag_params.totalValue.replace（'$'，''）;
