使用jQuery each（）函数循环遍历classname元素

I am trying to use jQuery to loop through a list of elements that have the same classname & extract their values.

我正在尝试使用jQuery循环遍历具有相同类名的元素列表并提取其值。

I have this..

我有这个..

function calculate() {

    // Fix jQuery conflicts
    jQuery.noConflict();

    jQuery(document).ready(function(){    

        // Get all items with the calculate className
        var items = jQuery('.calculate');



    });    

}

I was reading up on the each() function though got confused how to use it properly in this instance.

我正在阅读each()函数,虽然在这个例子中混淆了如何正确使用它。

1 个解决方案

#1

jQuery('.calculate').each(function() {
    var currentElement = $(this);

    var value = currentElement.val(); // if it is an input/select/textarea field
    // TODO: do something with the value
});

and if you wanted to get its index in the collection:

如果你想在集合中获得它的索引:

jQuery('.calculate').each(function(index, currentElement) {
    ...
});

Reference: .each() and .val() functions.

参考:.each()和.val()函数。
