如何使用Jquery自定义命名空间namespace

2022-01-31 01:22:37

// 把生成命名空间的方法绑定在jQuery上  

jQuery.namespace = function 
() {

    var 
a = arguments, o = null, i, j, d;

    for 
(i = 0; i < a.length; i = i + 1) {

        d = a[i].split(".");

        o = jQuery;

        for 
(j = (d[0] == "jQuery") ? 1 : 0; j < d.length; j = j + 1) {

            o[d[j]] = o[d[j]] || {};

            o = o[d[j]];

        }

    }

    return 
o;
};
 

jQuery.namespace(‘jQuery.UnionMedical.Tools‘);
//格式化金额

jQuery.UnionMedical.Tools.FormatMoney = function 
(v) {

    v = (Math.round((v - 0) * 100)) / 100;

    v = (v == Math.floor(v)) ? v + ".00" 
: ((v * 10 == Math.floor(v * 10)) ? v + "0" 
: v);

    v = String(v);

    var 
ps = v.split(‘.‘);

    var 
whole = ps[0];

    var 
sub = ps[1] ? ‘.‘ 
+ ps[1] : ‘.00‘;

    var 
r = /(\d+)(\d{3})/;

    while 
(r.test(whole)) {

        whole = whole.replace(r, ‘$1‘ 
+ ‘,‘ 
+ ‘$2‘);

    }

    v = whole + sub;

    if 
(v.charAt(0) == ‘-‘) {

        return 
‘-‘ 
+ v.substr(1);

    }

    return 
v;
};
