[英]jQuery radio button change when unchecked
I'm trying to toggle a radio button with Rails & jQuery.我正在尝试使用 Rails 和 jQuery 切换单选按钮。 Works great with checkboxes but not with radio buttons.
适用于复选框,但不适用于单选按钮。
Basically it does not refresh if billable is unchecked如果未选中 billable ,基本上它不会刷新
<%= f.radio_button :billable, 'true', :checked => true, :id => 'billable' %> This is a Billable Project <br />
<%= f.radio_button :billable, 'false' %> This is an Internal Project
<script type="text/javascript" charset="utf-8">
$(document).ready(function(){
$("#billable").change(function() {
$("#billing").toggle();
} );
});
</script>
by setting :checked => true its forced to always be true 通过设置:checked => true它被强制始终为true
for correctly setting the default value in controller 用于在控制器中正确设置默认值
def new
@event = Event.new(:billable => true)
end
then in view 然后来看
<%= f.radio_button :billable, 'true' %> This is a Billable Project <br />
<%= f.radio_button :billable, 'false' %> This is an Internal Project
Try this 尝试这个
$(document).ready(function(){
$("#billable").click(function() {
$("#billing").toggle(this.checked);
} );
});
This is what you want. 这就是你想要的。
$(document).ready(function(){
$("input[name=billable]").change(function() {
$("#billing").toggle();
} );
});

Try this please请试试这个
var whichChecked = "";
$('.radio').on('change', function() {
// if radio is checked, decrement variable associated with radio's value
if($(this).is(':checked')) {
if ($(this).val() === "int1") {
int1--;
}
if ($(this).val() === "int2") {
int2--;
}
if ($(this).val() === "int3") {
int3--;
}
if ($(this).val() === "int4") {
int4--;
}
whichChecked = $(this).val();
}
// when unchecked, increment variable associated with radio's value, doesn't work!
if (whichChecked === "int1") {
int1++;
}
if (whichChecked === "int2") {
int2++;
}
if (whichChecked === "int3") {
int3++;
}
if (whichChecked === "int4") {
int4--;
}
});
