使用jQuery从网页获取所有包含数字数据的元素？

Question

I was wondering, is there any way that I can get all the elements ie div s span s etc containing the numeric data? What I want to do is get all of them and then format them using a currency formatter jquery plugin. The code that I'm using now is:

var options = {
    symbol: "",
    decimal: ".",
    thousand: ",",
    precision: 2,
    format: "%s%v"
};

$(".namount").each(function () {
    var formattedNum = accounting.formatMoney($(this).text(), options)
    $(this).html(formattedNum);
});

$(".totalsale").each(function(){
    var formattedNum = accounting.formatMoney($(this).text(), options)
    $(this).html(formattedNum);
});

$(".totalpurchase").each(function(){
    var formattedNum = accounting.formatMoney($(this).text(), options)
    $(this).html(formattedNum);
});    

There are 4 to 5 more similar calls to each loop for different elements. The problem is, doing this won't be efficient. Is there any other way that I can achieve this.

Thanks

Answer 1

Since you have a class selector this is one of the best ways. Only change I would do is to use a multiple selector and the use the .text() method to update the value in the element

$(".namount, .totalsale, .totalpurchase").text(function (idx, text) {
    return accounting.formatMoney(text, options)
});

Another possible change you can think of is to narrow down the search context using a parent container element

You can do this by using class selector as suggested or you can achieve this using regular expression too.
