There are two different ways to use js to select all and unselect a checkbox:
Method one:
1: js implementation of checkbox selection function:
2: js to implement the anti-selection function of checkbox:
Method one:
1: js implementation of checkbox selection function:
function checkAll()
{
var code_Values = document.getElementsByTagName("input");
for(i = 0;i < code_Values.length;i++){
if(code_Values[i].type == "checkbox")
{
code_Values[i].checked = true;
}
}
}
2: js to implement the anti-selection function of checkbox:
function uncheckAll()
{
var code_Values = document.getElementsByTagName("input");
for(i = 0;i < code_Values.length;i++){
if(code_Values[i].type == "checkbox")
{
code_Values[i].checked = false;
}
}
}
