jqGrid在编辑时访问单元格数据

时间:2011-02-25 18:51:47

标签: javascript jquery jqgrid

我目前正在使用afterSaveCell来处理手动更新网格中的某些单元格。如果用户使用enter保存当前编辑的单元格,我可以正常工作。

不幸的是,如果他们点击或跳出他们正在直接编辑到另一个单元格的单元格,我就不能再抓取新编辑的单元格的单元格值,因为getCell只会返回输入控件的html。

总之,即使在编辑单元格时,有没有办法访问单元格的值?

jQuery(document).ready(function () {
    var mydata = [
        {id:"1", invdate:"2007-10-01",name:"test",  note:"note",  amount:"200.00",tax:"10.00",total:"210.00"},
        {id:"2", invdate:"2007-10-02",name:"test2", note:"note2", amount:"300.00",tax:"20.00",total:"320.00"},
        {id:"3", invdate:"2007-09-01",name:"test3", note:"note3", amount:"400.00",tax:"30.00",total:"430.00"},
        {id:"4", invdate:"2007-10-04",name:"test",  note:"note4", amount:"200.00",tax:"10.00",total:"210.00"},
        {id:"5", invdate:"2007-10-05",name:"test5", note:"note5", amount:"300.00",tax:"20.00",total:"320.00"},
        {id:"6", invdate:"2007-09-06",name:"test",  note:"note6", amount:"400.00",tax:"30.00",total:"430.00"},
        {id:"7", invdate:"2007-10-04",name:"test7", note:"note7", amount:"200.00",tax:"10.00",total:"210.00"},
        {id:"8", invdate:"2007-10-03",name:"test8", note:"note8", amount:"300.00",tax:"20.00",total:"320.00"},
        {id:"9", invdate:"2007-09-01",name:"test",  note:"note9", amount:"400.00",tax:"30.00",total:"430.00"},
        {id:"10",invdate:"2007-09-08",name:"test10",note:"note10",amount:"500.00",tax:"30.00",total:"530.00"},

        {id:"12",invdate:"",name:"TOTAL",  note:"",amount:"",tax:"",total:""}
    ];

    var grid = $("#list");

    grid.jqGrid({

        afterSaveCell: function (rowid, name, val, iRow, iCol) {
            calculateTotal();
        }

function calculateTotal() {
    var totalAmount = 0;
    var totalTax = 0;

    var grid = jQuery("#list");

    var ids = grid.jqGrid('getDataIDs');
    for (var i = 0; i < ids.length; i++) {
        var id = ids[i];

我在你的代码中看到两个问题。第一个更具外观,但正确的解决方案可以在未来简化许多事情。

第一个问题是您将“TOTAL”行手动添加为网格数据的一部分,并计算calculateTotal函数内的行中的值。更好的方法是使用footerrow:true选项,该选项会在网格底部添加额外的行,该行将与网格数据不混合。对于基于服务器的数据,您可以使用来自服务器的userdata部分JSON或XML响应,并另外使用userDataOnFooter:true直到将userData jqGrid参数中的数据添加到页脚行。对于“本地”数据类型,可以使用footerData方法设置(或获取)页脚中的数据。此外,方法getCol可用于计算列中元素的总和。因此,您的calculateTotal函数版本可以重写为

var grid = $("#list");
var calculateTotal = function() {
    var totalAmount = grid.jqGrid('getCol','amount',false,'sum'),
        totalTax = grid.jqGrid('getCol','tax',false,'sum');
    grid.jqGrid('footerData','set',{name:'TOTAL',amount:totalAmount,tax:totalTax});
}

现在你的主要问题。您使用单元格编辑模式。如果在“金额”或“税”的单元格中的一个处于编辑模式时,将调用函数calculateTotal(您的原始版本或我的简化版本),calculateTotal将是读取带有<input>元素的HTML片段而不是带有数字的字符串,计算将失败。

我创建the small demo,每秒呼叫calculateTotal。所以,如果你点击任何单元格 'amount'或'tax'列您将看到在页脚行0中将显示为总和。因此,cellsubmit:'clientArray'的示例与使用cellsubmit:'remote'的原始代码存在同样的问题。

要解决此问题,可以在求和过程中使用jqGrid的data参数:

var grid = $("#list");
var calculateTotal = function() {
    var gridData = grid.jqGrid('getGridParam','data'),
        i=0,totalAmount=0,totalTax=0;
    for (;i<gridData.length;i++) {
        var rowData = gridData[i];
        totalAmount += Number(rowData.amount);
        totalTax += Number(rowData.tax);
    }
    grid.jqGrid('footerData','set',{name:'TOTAL',amount:totalAmount,tax:totalTax});
}

您将找到相应的固定演示here。在您的最终代码中,您可以删除

setInterval(calculateTotal, 1000);

我仅用于演示目的,仅刷新afterSaveCell事件处理程序中的页脚。

更新:如果使用远程数据,则无法使用data参数。因此,如果需要,必须从<input>元素获取数据。我创建了one more demo,演示了如何做到这一点。 calculateTotal的代码会更长:

var getColumnIndexByName = function(grid,columnName) {
    var cm = grid.jqGrid('getGridParam','colModel');
    for (var i=0,l=cm.length; i<l; i++) {
        if (cm[i].name===columnName) {
            return i; // return the index
        }
    }
    return -1;
},
getTextFromCell = function(cellNode) {
    return cellNode.childNodes[0].nodeName === "INPUT"?
           cellNode.childNodes[0].value:
           cellNode.textContent || cellNode.innerText;
},
calculateTotal = function() {
    var totalAmount = 0, totalTax = 0,
        i=getColumnIndexByName(grid,'amount');
    $("tbody > tr.jqgrow > td:nth-child("+(i+1)+")",grid[0]).each(function() {
        totalAmount += Number(getTextFromCell(this));
    });

    i=getColumnIndexByName(grid,'tax');
    $("tbody > tr.jqgrow > td:nth-child("+(i+1)+")",grid[0]).each(function() {
        totalTax += Number(getTextFromCell(this));
    });

    grid.jqGrid('footerData','set',{name:'TOTAL',amount:totalAmount,tax:totalTax});
};

谢谢你,我的解决方案就是应用并改变你所放的东西

var cm = $("#"+grid).jqGrid('getGridParam','colModel');
for (var i=0,l=cm.length; i<l; i++) {
    if (cm[i].name===columnName) {
        return i; // return the index
    }
}
return -1;
},

getTextFromCell = function(cellNode) {
return cellNode.childNodes[0].nodeName === "INPUT"?
       cellNode.childNodes[0].value:
       cellNode.textContent || cellNode.innerText;
},

calculateTotal = function(grid) {

答案 2 :(得分:1)

如果您只想重新计算总数,可以使用触发器在afterSaveCell事件中重新加载网格。像这样:

afterSaveCell: function (rowid, name, val, iRow, iCol) 

        {
          jQuery("#list11").jqGrid('setGridParam',{datatype:'local',loadonce:true}).trigger('reloadGrid');
        }
