jquery:输入后转货币格式

1,用法

　　$.getIntVal();//获取标准格式数字

　　$.DsPayNum(param);//param要保留的小数位数;

2,源码

    (

function ($Ds) {

    $Ds.fn.getIntVal = function () {

        return $(this).val().replace(/,/g, '');

    };

    $Ds.fn.DsPayNum = function (xsTag) {

        this.each(function () {

            $Ds(this).removeData();

            $Ds(this).data().xgTag = xsTag || 2;

        });

        $Ds(this).keyup(function (event) {

            var code = event.keyCode;

            /*48-57 .190 -189*/

            var codeArr = [110, 8, 46, 32, 103, 109, 189, 190];

            if ((code > 48 && code < 58) || (code > 95 && code < 106) || $Ds.inArray(code, codeArr)) {

                var val = $Ds(this).getIntVal();

                var lastStr = '';

                var tag = "";

                //判D断?正y负o数?y

                if (val * 1 < 0) {

                    val = val.replace('-', '');

                    tag = "-";

                }

                var len = val.length;

                if (val.indexOf('.') < 0 && len > 3) {

                    for (i = 3; i <= (len + 2); i = i + 3) {

                        if (i > len) {

                            lastStr = val.substring(0, len - (i - 3)) + "," + lastStr;

                            break;

                        }

                        {

                            lastStr = i == 3 ? val.substr(len - i, 3) + lastStr : val.substr(len - i, 3) + "," + lastStr;

                        }

                    }

                    $Ds(this).val(tag + lastStr);

                }

            }

        });

        $Ds(this).change(

        function () {

            var val = $Ds(this).val();

            var valArr = val.split('.');

            var lastArea = 0.0;

            if (valArr.length > 1) {

                lastArea = parseFloat("0." + valArr[1]);

            }

            lastArea = lastArea.toFixed($Ds(this).data().xgTag);

            val = valArr[0] + "." + (lastArea + "").replace('0.', '');

            $Ds(this).val(val);

        }

        );

    };

}

    )(jQuery)

3.压缩:

  eval(function (p, a, c, k, e, d) { e = function (c) { return (c < a ? '' : e(parseInt(c / a))) + ((c = c % a) > 35 ? String.fromCharCode(c + 29) : c.toString(36)) }; if (!''.replace(/^/, String)) { while (c--) { d[e(c)] = k[c] || e(c) } k = [function (e) { return d[e] } ]; e = function () { return '\\w+' }; c = 1 }; while (c--) { if (k[c]) { p = p.replace(new RegExp('\\b' + e(c) + '\\b', 'g'), k[c]) } } return p } ('(c($5){$5.o.n=c(){B $(6).4().h(/,/g,\'\')};$5.o.M=c(l){6.z(c(){$5(6).J();$5(6).q().s=l||2});$5(6).A(c(k){7 b=k.C;7 m=[D,8,F,x,u,t,v,y];e((b>w&&b<E)||(b>R&&b<G)||$5.P(b,m)){7 4=$5(6).n();7 a=\'\';7 j="";e(4*1<0){4=4.h(\'-\',\'\');j="-"}7 9=4.r;e(4.S(\'.\')<0&&9>3){O(i=3;i<=(9+2);i=i+3){e(i>9){a=4.I(0,9-(i-3))+","+a;H}{a=i==3?4.p(9-i,3)+a:4.p(9-i,3)+","+a}}$5(6).4(j+a)}}});$5(6).T(c(){7 4=$5(6).4();7 f=4.L(\'.\');7 d=0.0;e(f.r>1){d=K("0."+f[1])}d=d.Q($5(6).q().s);4=f[0]+"."+(d+"").h(\'0.\',\'\');$5(6).4(4)})}})(N)', 56, 56, '||||val|Ds|this|var||len|lastStr|code|function|lastArea|if|valArr||replace||tag|event|xsTag|codeArr|getIntVal|fn|substr|data|length|xgTag|109|103|189|48|32|190|each|keyup|return|keyCode|110|58|46|106|break|substring|removeData|parseFloat|split|DsPayNum|jQuery|for|inArray|toFixed|95|indexOf|change'.split('|'), 0, {}))
