在网格加载后对焦或选择该行

Question

• 我有一个带有按钮的jsp页面。
• 点击该按钮，它会动态地创建一个dojo网格。
• 网格被加载后，我通过网格迭代，如果有特定的值，整个行被选中。
• 我通过使用下面的代码实现了它，行被选中，但出现错误。
• 错误： “错误：dojo.data.ItemFileReadStore：无效项的参数”
• 正在使用dojoX.grid.DataGrid（1.7）

下面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({ 
         field: key, 
         name: displayName[i], 
         formatter:function(opvalue){ 
          //alert(opvalue); 
          opvalue = parseInt(opvalue); 
          if(opvalue==1){ 
           return "Executing";} 
          if(opvalue==2){ 
           return "Suspended";}

         width: '200px',

Answer 1

此代码帮我在网格中选择行：

grid.selection.select(rowIndex); 

你的情况：

finderResponse.selection.select(rowIndex); 

我希望这能解决您的问题。

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(); 
}
