Question

我有一个带按钮的jsp页面。
单击该按钮，它会动态创建一个dojo网格。
网格加载后，我在网格中迭代，如果有特定值，则选择整行。
我使用下面的代码实现了它，行被选中，但是收到错误。
错误：“错误：dojo.data.ItemFileReadStore：无效的项目参数”
使用dojoX.grid.DataGrid（1.7）

以下是创建动态网格的代码：

var ioArgs = {
            url: "./DynamicDBServlet",
            content: { TABLE_NAME:tableName,WHERE_CONDN:condtn,COLUMNS:gridColumnName,ACTION:'select'}, 
            handleAs: "json",
            load: function(response) {
                //alert(response["items"][0].USER_ID);
                 var tbl = document.getElementById(gridID);
                 //alert(tbl);
                  if(tbl) tbl.parentNode.removeChild(tbl);
                var gridLayout = [];
                var key;
                colmn=gridColumnName.split(',');
                var i=0;
                while(i<colmn.length)  {
                    if(colmn[i]=="STATUS"){
                        key = colmn[i];
                        gridLayout.push({

Answer 1

此代码帮助我选择网格中的行：

grid.selection.select(rowIndex);

在你的情况下：

finderResponse.selection.select(rowIndex);

我希望这能解决你的问题。

Answer 2

function selectRowByYourOwn(){
var row = null;

// you have to get is some have.. try onSelected='yourOwnFn', on your table tag or your div tag.
// function yourOwnFn(rowID){ row = rowID;}

grid.selection.clear();
grid.selection.setSelected(row, true);
grid.render();
}

在网格加载后聚焦或选择行
