Idea: Use the name attribute value to obtain the checkbox object, and then loop to determine the checked attribute (true means selected, false means unchecked). Here is an example demonstration:
1, HTML structure
<input type="checkbox" name="test" value="1" />
<span>
1
</span>
<input type="checkbox" name="test" value="2" />
<span>
2
</span>
<input type="checkbox" name="test" value="3" />
<span>
3
</span>
<input type="checkbox" name="test" value="4" />
<span>
4
</span>
<input type="checkbox" name="test" value="5" />
<span>
5
</span>
<input type='button' value='提交' onclick="show()" />2, javascript code (jQuery)
function show(){
obj = document.getElementsByName("test");
check_val = [];
for(k in obj){
if(obj[k].checked)
check_val.push(obj[k].value);
}
alert(check_val);
}3. Demonstration effect
