I saw this on jsfiddle and I wanted to know how I would alter it so that if and only if 45 is checked the rest are disabled, if if 45 is unselected then the rest are enabled. I should be able to do all this with out submitting the form.
The example javascript on jsfiddle:
$(function(){
$(".rambo").change(function(){
$(this).siblings().attr("disabled", $(this).is(":checked"));
});
});
You can use attribute selector
.
$(function(){
$(".rambo[value=1]").change(function(){
$(this).siblings().prop("disabled", this.checked);
});
});
从其他人中删除.rambo类。
$(function(){
$(".rambo").change(function(){
if($(this).val() == 1){
$(this).siblings().attr("disabled", $(this).is(":checked"));
}
});
});
One way
Above from all the answers, you can also specify that you only want the 1st checkbox
to execute the script by using nth-child
selector:
$(".rambo:nth-child(1)").change(function(){
$(this).siblings().attr("disabled", $(this).is(":checked"));
});
Just add proper id
s and select on that
HTML:
<input type="checkbox" id="cb1" class="rambo" value='1' /> 45
<input type="checkbox" id="cb2" class="rambo" value='2' /> 56
<input type="checkbox" id="cb3" class="rambo" value='3' /> 56
JS:
$(function(){
$("#cb1").change(function(){
$(this).siblings().attr("disabled", $(this).is(":checked"));
});
});
