</div>
<!--遮罩层开始-->
<div id="i1" class="c1 hide"></div>
<!--遮罩层结束-->
<!--弹出框开始-->
<div id="i2" class="c2 hide">
<p><input type="text"/></p>
<p><input type="text"/></p>
<p>
<input type="button" value="取消" onclick="HideModel();"/>

<!--弹出框结束-->
<script>
function ShowModel() {
document.getElementById("i1").classList.remove("hide");
document.getElementById("i2").classList.remove("hide");
}
function HideModel() {
document.getElementById("i1").classList.add("hide");
document.getElementById("i2").classList.add("hide");
}
function ChooseAll() {
var tbody = document.getElementById("tb");
var tb_list = tbody.children;
for (var i = 0; i < tb_list.length; i++) {
var current_tr = tb_list[i];
var checkbox = current_tr.children[0].children[0];
checkbox.checked = true;
}
}
function CancelAll() {
var tbody = document.getElementById("tb");
var tb_list = tbody.children;
for (var i = 0; i < tb_list.length; i++) {
var current_tr = tb_list[i];
var checkbox = current_tr.children[0].children[0];
checkbox.checked = false;
}
}
function ReverseAll() {
var tbody = document.getElementById("tb");
var tb_list = tbody.children;
for (var i = 0; i < tb_list.length; i++) {
var current_tr = tb_list[i];
var checkbox = current_tr.children[0].children[0];
if(checkbox.checked){
checkbox.checked = false;
}else{
checkbox.checked = true;
}
}
}
</script>
</body>
