我需要在jQuery中创建一个简单的函数,它将在其他几个函数中调用
$(document).ready(function() {
function reload_cart() {
alert('reload cart called');
}
});
$(document).ready(function() {
reload_cart(); //i need to call from here.
});
$(document).ready(function() {
$('a.add_to_cart').live('click', function (e) {
reload_cart(); //i need to call from here.
});
});

我在萤火虫中得到的错误:reload_cart() is not defined.
jQuery的:
$(document).ready(function() {
$("a.change_status").click(function(){
var status_id = $("a").val();
alert(status_id);
return false;
});
});

我需要status_id并且出于某种原因我的锚标签是动态的.我不能使用id或make class name dynamic.我想,我需要$this用来获得我的价值.
<script>
$(document).ready(function(){
//Load City by State
$('#billing_state_id').live('change', function() {
//do something
});
$('#click_me').live('click', function() {
//do something
//need to recall $('#billing_state_id').live('change', function() { but how?
});
});
</script>

我需要一个简单的运算符重载示例.不使用类或结构.在这里,我尝试但得到错误:
#include <iostream.h>
int operator+(int a, int b)
{
return a-b;
}
void main()
{
int a,b,sum;
cin>>a>>b;
sum=a+b; //Actually it will subtruct because of + operator overloading.
cout<<"Sum of "<<a<<" & "<<b<<"(using overloading)"<<sum;
}

让我知道是否有可能重载运算符(sum = a + b)?如果是,那么请在我的来源中进行更正.
