我如何为jqGrid中的列赋值?

标签: javascript codeigniter jquery jqgrid

我正在使用带有CodeIgniter 2.1.0的jqGrid。 让我受到骚扰的是如何为特定事件的特定列分配值

假设我输入数量并按列值进行评分.....当我从“费率”字段中失去焦点时......应计算净额并显示在金额字段中......

我需要做的是将计算值分配给金额字段......但我不知道我该怎么办?

我所做的事情如下:

var selIRow = 1;
var rowid='';
var iCol='';
$("#purchasedetailsgrid").jqGrid({
    url: sitepath + 'purchase/purchase_grid',
    datatype: 'json',
    mtype: 'POST',
    height:220,
    width:500,
    colNames:["","","Store Name","Item Name","Inner Pkg.","Outer Pkg.","Qty","Rate","Amount"],
    colModel:[
        {name: 'storeID_hidden_field', index:'storeID_hidden_field',hidden: true, editable: true,edittype: 'text',editrules: {edithidden:true}},
        {name: 'itemID_hidden_field', index:'itemID_hidden_field',hidden: true, editable: true,edittype: 'text',editrules: {edithidden:true}},
        {name:'store_id', index:'store_id',width:150,search:false,editable:true,editrules:{number:false,maxlength:10}},
        {name:'item_id', index:'item_id',width:150,search:false,editable:true,editrules:{number:false,maxlength:10}},
        {name:'inner_pkg', index:'inner_pkg',width:150,search:false,editable:true,editrules:{number:true,maxlength:5}},
        {name:'outer_pkg', index:'outer_pkg',width:150,search:false,editable:true,editrules:{number:true,maxlength:5}},
        {name:'qty', index:'qty',editable:true,width:85,search:false,editrules:{number:true,maxlength:5}},
        {name:'rate', index:'rate',width:100,editable:true,search:false,editrules:{number:true,maxlength:10},
            editoptions: {
                dataInit: function (elem) { $(elem).focus(function () { this.select(); }) },
                dataEvents: [
                    {
                        type: 'keydown',
                        fn: function (e) {
                            var key = e.charCode || e.keyCode;
                            if (key == 9)//tab
                            {
                                $('#amount').val();//here in val() i need to write the value of qty and rate field
                            }
                        }
                    }
                ]
            }
        },
        {name:'amount', index:'amount',width:100,editable:true,search:false,editrules:{number:true,maxlength:10},
            editoptions: {
                dataInit: function (elem) { $(elem).focus(function () { this.select(); }) },
                dataEvents: [
                    {
                        type: 'keydown',
                        fn: function (e) {
                            var key = e.charCode || e.keyCode;
                            if (key == 13)//enter
                            {
                                var grid = $('#purchasedetailsgrid');
                                //Save editing for current row

                                grid.jqGrid('saveRow', selIRow, false, sitepath + 'purchase/purchase_grid');
                                selIRow++;
                                //If at bottom of grid, create new row
                                //if (selIRow++ == grid.getDataIDs().length) {

                            }
                        }

现在有人可以建议我如何从一个专栏中获取价值并将其分配给另一个专栏?

任何建议都将受到赞赏。

答案 0 :(得分:1)

您当前的代码有很多问题。例如,您写道,您需要根据数量和费率计算金额,但您在'rate'和'amount'列中定义了一些dataEvents,而不是'qty'和'rate'列。您在editRow内直接使用gridComplete方法的下一个问题。因此inlineNav工具栏中的按钮将保持错误状态。还有一个问题是,你需要根据'qty'和'rate'重新计算'amount',不仅要考虑'qty'和'rate'失去焦点,还需要保存 Enter <上的值。 / KBD>

为了更容易解决上述问题,我编写了the demo,您可以根据自己的具体要求进行修改。您可以在下面找到演示中最重要的部分:

var editingRowId = undefined,
    recomputeAmount = function () {
        var rate = $("#" + editingRowId + "_rate").val(),
            qty = $("#" + editingRowId + "_qty").val(),
            newAmount = parseFloat(rate) * parseFloat(qty);
        $("#" + editingRowId + "_amount").val(isFinite(newAmount) ? newAmount : 0);
    },
    myEditParam = {
        keys: true,
        oneditfunc: function (id) {
            editingRowId = id;
        },
        afterrestorefunc: function (id) {
            editingRowId = undefined;
        },
        aftersavefunc: function (id) {
            var $this = $(this),
                rate = $this.jqGrid("getCell", id, "rate"),
                qty = $this.jqGrid("getCell", id, "qty"),
                newAmount = parseFloat(rate) * parseFloat(qty);
            $this.jqGrid("setCell", id, "amount", newAmount);
            editingRowId = undefined;
        }
    },
    numInput = {
        type: 'keydown',
        fn: function (e) {
            var key = e.which;
            // allow only '0' <= key <= '9' or key = '.', Enter, Tab, Esc
            if ((key < 48 || key > 57) && key !== $.ui.keyCode.PERIOD &&
                key !== $.ui.keyCode.TAB && key !== $.ui.keyCode.ENTER && key !== $.ui.keyCode.ESCAPE) {
                return false;
            }
        }
    },
    recompute = {
        type: 'focusout',
        fn: function (e) {
            recomputeAmount();
        }
    };
$("#purchasedetailsgrid").jqGrid({
    colModel: [ 
        ...
        {name:'qty', index:'qty',editable:true,width:85,search:false,editrules:{number:true,maxlength:5},
            editoptions: {
                dataInit: function (elem) { $(elem).focus(function () { this.select(); }) },
                dataEvents: [ numInput, recompute ]
            }
        },
        {name:'rate', index:'rate',width:100,editable:true,search:false,editrules:{number:true,maxlength:10},
            editoptions: {
                dataInit: function (elem) { $(elem).focus(function () { this.select(); }) },
                dataEvents: [ numInput, recompute ]
            }
        },
        {name:'amount', index:'amount',width:100,editable:true,search:false,editrules:{number:true,maxlength:10}}
    ],
    loadComplete: function () {
        var gridIdSelector = '#' + $.jgrid.jqID(this.id);
        if (this.rows.length > 1) {
            //$(this).jqGrid('editRow', this.rows[1].id, myEditParam);
            $(this).jqGrid('setSelection', this.rows[1].id, true);
            setTimeout(function() {
                // we should simulate click of the button not after the grid is loaded, but
                // after the toolbar with the cliked button will be created by inlineNav
                $(gridIdSelector + "_iledit").click();
            }, 100);
        } else {
            setTimeout(function() {
                // we should simulate click of the button not after the grid is loaded, but
                // after the toolbar with the cliked button will be created by inlineNav
                $(gridIdSelector + "_iladd").click();
            }, 100);
        }
    }
 }); 
 jQuery("#purchasedetailsgrid").jqGrid('navGrid','#purchasedetailstoolbar',
     {view:false,edit:false,add:false,del:false,search: false, refreshtitle: "Reload Grid"});
 jQuery("#purchasedetailsgrid").jqGrid('inlineNav','#purchasedetailstoolbar',
     {edit: true, add: true, editParams: myEditParam, addParams: {addRowParams: myEditParam}});

如果需要,我可以评论代码中不清楚的部分。
