循环删除多行时，只删除了第一行，Help

Question

代码如下：function moveToKHSozai() {    var junniColumnCount = junniGrid.getColumnCount();
    for(var i = 0; i < junniGrid.getRowsNum(); i++) {
        if (junniGrid.cellByIndex(i, 0).getValue() != '') {
            alert(i);
            var tmpjunniData = "";
            for (var k = 2; k < junniColumnCount; k++) {
                tmpjunniData = tmpjunniData + "," + junniGrid.cellByIndex(i, k).getValue() 
            }
            //kouhoGrid.addRow("",tmpjunniData,kouhoGrid.getRowsNum());
            junniGrid.deleteRow(i);
            i--;
        }
    }
       
}

Answer 1

function moveToKHSozai() {     var junniColumnCount = junniGrid.getColumnCount(); 
    for(var i = junniGrid.getRowsNum()-1;i>=0;) { 
        if (junniGrid.cellByIndex(i, 0).getValue() != '') { 
            alert(i); 
            var tmpjunniData = ""; 
            for (var k = 2; k < junniColumnCount; k++) { 
                tmpjunniData = tmpjunniData + "," + junniGrid.cellByIndex(i, k).getValue() 
            } 
            //kouhoGrid.addRow("",tmpjunniData,kouhoGrid.getRowsNum()); 
            junniGrid.deleteRow(i); 
            i--; 
        } 
    } 
      
}

Answer 2

 junniGrid.deleteRow(i); 
在这上边打印I，能输出几次呢

Answer 3

这样不行，他在嵌套循环里还要用i，楼主，你看看这样行不行：
for(var i = 0; i < junniGrid.getRowsNum(); ) {
        if (junniGrid.cellByIndex(i, 0).getValue() != '') {
            alert(i);
            var tmpjunniData = "";
            for (var k = 2; k < junniColumnCount; k++) {
                tmpjunniData = tmpjunniData + "," + junniGrid.cellByIndex(i+1, k).getValue();//这里不要用i++，不然i的值又变了
            }
            //kouhoGrid.addRow("",tmpjunniData,kouhoGrid.getRowsNum());
            junniGrid.deleteRow(i);
        } 

Answer 4

反着删的话，你里面那个嵌套循环也得改，不然tmpjunniData的内容就不对了
