javascript function for checkbox checked event
提问by h_a86
I need a function that can add checkbox values on click event. My html code is
我需要一个可以在单击事件上添加复选框值的函数。我的 html 代码是
<div data-role="fieldcontain">
<fieldset data-role="controlgroup">
<center><b> Plattforms </b></center>
<input type="checkbox" name="cbs" id="cbs" value = 945345 />
<label for="cbs">945345 Symbian</label>
<input type="checkbox" name="cbi" id="cbi" value = 945345 />
<label for="cbi">945345 iPhone</label>
<input type="checkbox" name="cbb" id="cbb" value = 945345 />
<label for="cbb">945345 Blackberry</label>
<input type="checkbox" name="cba" id="cba" value = 945345 />
<label for="cba">945345 Android</label>
<input type="checkbox" name="cbw" id="cbw" value = 945345 />
<label for="cbw">945345 Windows Mobile</label>
<input type="checkbox" name="cbo" id="cbo" value = 945345 />
<label for="cbo">945345 All Other</label>
</fieldset>
</div>
The logic is when a user click on a checkbox, the checkbox value goes to a variable and again the user if clicks on another checkbox that value adds up into first value. Thanks in advance
逻辑是当用户单击复选框时，复选框值转到变量，如果用户单击另一个复选框，则该值加起来为第一个值。提前致谢

Do you mean like:
你的意思是像：
var total = 0;
$("input[type='checkbox']").click(function() {
//if you want to add on checked
if($(this).is(":checked")) {
var v = parseInt($(this).val(), 10);
total += v;
}
else {
total -= v;
}
});
Hope it helps
希望能帮助到你

You could do;
你可以这样做；
var tot = 0;
$("input:checkbox").click(function() {
var val = parseInt(this.value, 10);
if($(this).is(":checked")) {
//add to total if it's checked
tot += vale;
}else{
//this was previously checked, subtract it's value from total
tot -= vale;
}
});
