DWZ主从结构计算

最终效果图：

首先我们需要修改一下主从结构的源码dwz.database.js，如下：

function tdHtml(field){
                var html='',suffix='';
                if(field.name.endsWith("[#index#]"))suffix="[#index#]";
                else if(field.name.endsWith("[]"))suffix="[]";
                var suffixFrag=suffix?' suffix="'+suffix+'" ':'';
                switch(field.type){
                    case 'del':
                        html='<a href="#" onclick="calculate(this, 1);" class="btnDel '+field.fieldClass+'">刪除</a>';
                        break;
                    case 'lookup':
                        var suggestFrag='';
                        if(field.suggestFields){
                            suggestFrag='autocomplete="off" lookupGroup="'+field.lookupGroup+'"'+suffixFrag+' suggestUrl="'+field.suggestUrl+'" suggestFields="'+field.suggestFields+'"'+' postField="'+field.postField+'"';}
                        html='<input type="hidden" name="'+field.lookupGroup+'.'+field.lookupPk+suffix+'"/>'+'<input type="text" name="'+field.name+'"'+suggestFrag+' lookupPk="'+field.lookupPk+'" size="'+field.size+'" class="'+field.fieldClass+'" '+field.readOnly+' />'+'<a class="btnLook" href="'+field.lookupUrl+'" lookupGroup="'+field.lookupGroup+'" '+suggestFrag+' lookupPk="'+field.lookupPk+'" title="查找帶回">查找?回</a>';
                        break;
                    case 'attach':
                        html='<input type="hidden" name="'+field.lookupGroup+'.'+field.lookupPk+suffix+'"/>'+'<input type="text" name="'+field.name+'" size="'+field.size+'" class="'+field.fieldClass+'" '+field.readOnly+' />'+'<a class="btnAttach" href="'+field.lookupUrl+'" lookupGroup="'+field.lookupGroup+'" '+suggestFrag+' lookupPk="'+field.lookupPk+'" width="560" height="300" title="查找?回">查找?回</a>';
                        break;
                    case 'enum':
                        $.ajax({
                            type:"POST",dataType:"html",async:false,
                            url:field.enumUrl,
                            data:{inputName:field.name},
                            success:function(response){
                                html=response;}});
                        break;
                    case 'date':
                        html='<input type="text" name="'+field.name+'" value="'+field.defaultVal+'" class="date '+field.fieldClass+'" format="'+field.patternDate+'" size="'+field.size+'" '+field.readOnly+' />'+'<a class="inputDateButton" href="javascript:void(0)">??</a>';
                        break;
                    case 'lab':
                        html='<label>' + field.defaultVal + '</label>';
                        break;
                    case 'calculate':
                        html = '<input type="text" name="' + field.name + '" value="' + field.defaultVal + '" size="' + field.size + '" onkeyup="calculate(this, 0);" class="' + field.fieldClass + '" '+field.readOnly+' />';
                        break;
                    default:
                        html='<input type="text" name="'+field.name+'" value="'+field.defaultVal+'" size="'+field.size+'" class="'+field.fieldClass+'" '+field.readOnly+' />';
                        break;}
                return '<td nowrap="nowrap">'+html+'</td>';
            }

上面增加了一个calculate的文本类型，它加入onkeyup事件。

以下为Html部分代码：

<script type="text/javascript">
<!--
var total_amount = $("input[name=total_amount]");
var trade_amount = $("input[name=trade_amount]");
var odd_amount = $("input[name=odd_amount]");
var total_nums = $("input[name=total_nums]");
$(function(){

    // 初始化應收金額和實收金額
	total_amount.val((0).toFixed(2));
	trade_amount.val((0).toFixed(2));
    total_nums.val(0);

	// 扣除零頭
	odd_amount.keyup(function(){
		trade_amount.val((total_amount.val() - $(this).val()).toFixed(2));
	});
});

function calculate(t, del){
    var tbody = $(t).parents('tbody');
    var total = 0;
    var totalnums = 0;
    var fix = 0;
    var fixnums=0;// 刪除的話應該忽略本行
    if (del == 1){
        //alert(0);
        $(t).parents("tr:first").each(function(){
            var orgCount = 0;
            var orgPrice = 0;
            var orgDiscount = 1;
            var orgTotal = 0;
            $(this).find('input').each(function(){
                if (this.name == 'items.orgCount[]') orgCount = this.value == '' ? 0 : this.value;
                if (this.name == 'items.orgPrice[]') orgPrice = this.value == '' ? 0 : this.value;
                if (this.name == 'items.orgDiscount[]') orgDiscount = this.value == '' ? 1 : (1 - this.value/100);
                if (this.name == 'items.orgTotal[]'){
                    orgTotal = orgCount*orgPrice*orgDiscount;
                    if (orgTotal == 0){
                        this.value = '';
                    } else {
                        this.value = orgTotal.toFixed(2);
                    }
                }
            });
            fix = orgTotal;
            fixnums =orgCount;
        });
    }
    $(tbody).find('tr').each(function(){
        var orgCount = 0;
        var orgPrice = 0;
        var orgDiscount = 1;
        var orgTotal = 0;
        $(this).find('input').each(function(){
            if (this.name == 'items.orgCount[]') orgCount = this.value == '' ? 0 : 1*this.value;
            if (this.name == 'items.orgPrice[]') orgPrice = this.value == '' ? 0 : this.value;
            if (this.name == 'items.orgDiscount[]') orgDiscount = this.value == '' ? 1 : (1 - this.value/100);
            if (this.name == 'items.orgTotal[]'){
                orgTotal = orgCount*orgPrice*orgDiscount;
                if (orgTotal == 0){
                    this.value = '';
                } else {
                    this.value = orgTotal.toFixed(2);
                }
            }
        });
        total += orgTotal;
        totalnums +=orgCount;
    });
    if (fix != 0){
        total -= fix;
        totalnums -= fixnums;
    }
    total_nums.val(totalnums);
    total_amount.val(total.toFixed(2));
    trade_amount.val((total - odd_amount.val()).toFixed(2));
