3.JavaScript代码
function getYuan() {
//获取所有已选中元素序列
var spans = document.querySelectorAll('input[type="checkbox"]:checked');
var str = ""
//遍历元素序列
for (var i = 0; i < spans.length; i++) {
//获取父节点
var s = spans[i].parentNode;
//获取最近的祖先元素 tr
var trElement = s.closest('tr');
//是否获取到tr
if (trElement)
{
//获取当前tr下面所有td元素
var tdElements = trElement.querySelectorAll('td');
//遍历td元素
for(var j=0;j<tdElements.length;j++)
{
//获取特定元素
var inputElement=tdElements[j].querySelector("input[name='omorderdeliverheaderv.list.header_id']")
if (inputElement)
{
var value = inputElement.value;
//赋值
if (str == "")
{
str = str + value
}
else
{
str = str + "," + value
}
}
}
}
}
//显示元素的value
alert(str)
}
以上采用的是循环遍历的方式实现
