如何在javascript中获取item.count的datalist [英] how to get items.count of datalist in javascript

问题描述

我能够获得rows.length并且我循环遍历它以计算no.of单元格

i'm able to get rows.length and i' m looping through it in order to count no.of cells

for (i = 0; i < dlOption.rows.length; i++) {
                       n = n + dlOption.rows[i].cells.length
                   }

但这里的问题是



如果假设我的数据列表包含2行，每行有4列，那么我算得数为8


但实际上它包括两行中的5项，我必须在javascript中获得准确的项目数





其中dloption是我在viewsource中呈现的datalist

But here the problem is

if suppose my datalist contains 2 rows with four columns each, then I'm getting count as 8

But actually it cosnsits 5 items in two rows i have to get exact item count in javascript


where dloption is my rendered datalist in viewsource
