jQuery Character Counter使用类? [英] jQuery Character Counter using class?

问题描述

我有一个很长的表格，其中包含textareas字段，我想使用类选择器而不是ID来标识字段和每个字段的限制.现在，我正在工作:

I have a rather long form with textareas fields and I'd like to use a class selector instead of an ID to identify the fields and limits for each field. Right now, I have this working:

$(document).ready(function(){
    $("#TextAreaID").counter({
        goal: 500
    });
});

这适用于一个文本区域，但是由于我有多个文本区域，因此我想知道一种更好的方法，因为这不起作用:

and this works for one textarea but since I have several textarea's, I'd like to know a better way to do this since this doesn't work:

$(document).ready(function(){
    $(".limit500").counter({
        goal: 500
    });
});

我正在使用以下jQuery插件: http://meetups. jquery.com/profiles/blogs/jquery-word-and-character

推荐答案

遍历元素并将.counter应用于每个元素:

Loop through the elements and apply .counter to each:

$(document).ready(function(){
    $(".limit500").each(function() {
        $(this).counter({
            goal: 500
        });
    });
});
