Question

我正在使用dojo工具包版本1.10。我们有一个问题需要突出显示特定的单元格。我们可以在 onStyleRow 上突出显示一行。但有没有办法突出增强网格中的特定单元格？

已编辑：

对于格式化程序我已经做到了。这是我的格式化程序 -

var cellformatter = function(value){

     color = "green";

     return "<span style=color:green>" + value +"</span>;"
}

我将此绑定到我拥有的可用网格结构。

for (var i=0;i<gridStructure.length;i++)
{
    var gridData = gridStructure[i];

    gridData.formatter = cellformatter ;

}

在网格定义中我将它添加到结构中。 -

var mygrid = new EnhancedGrid({
    id: 'grid',
    store: gridStore, //Data store passed as input
    structure: gridData, //Column structure passed as input
    autoHeight: true,
    autoWidth: true
})

但如果我这样做，数据将无法显示。如果我在格式化程序值中使用作为字符串，我可以看到它处于警报状态，但如果使用某个函数，它根本就不会出现。我不知道这里有什么问题。

在这里，您可以看到excel工作表行突出显示，但不是该行的第一个单元格。同样，我希望将某种样式添加到特定单元格中。不是整行或列

Answer 3

我们可以在这里使用onStyleRow事件。我们只需要知道列号和行号。

这是代码

dojo.connect(grid, "onStyleRow", function(row){
     var nd = dojo.query('td[idx="1"]'  /* <= put column index here */, row.node)[0];
     if(nd){
            if(nd.innerHTML == 'FALSE' /* <= put cell content here */){
                nd.style.backgroundColor = "red";
              }else if(nd.innerHTML == "TRUE"){
                 nd.style.backgroundColor = "green";
                 }
            }
        });
