Integrated implementation code of dwr spring_javascript skills

1. Correct use of spring
1. Configuration of dwr.xml

Copy code The code is as follows:

<dwr>
<allow>
<!-- dwr spring -->
<create creator="spring" javascript="JCustomerManager">
<param name="beanName" value="customerManager"/>
</create>
</allow>
</dwr>

customerManager It is the Id
2 registered by spring, and the page calls

Copy code The code is as follows:

<script type="text/javascript">
function manager(){
JCustomerManager.deleteCustomer(1,function(){
alert("cg");} //Test
)
}
</script>

Second, explain
If the regular methods used in the business logic class customerManagerImpl.java will not be called by the static page, such as

Copy code The code is as follows:

public String test(){
return "hello" ;
}

The following code cannot be executed:

Copy code The code is as follows:

JCustomerManager.test(function(data){
alert(data);}
)
JCustomerManager.test(function(data){
alert(data);}
)

Need to use new registration method

Copy code The code is as follows:

<dwr>
<allow>
<!-- dwr spring -->
<create creator="new" javascript="JCustomerManager">
<param name="class" value="...XXX.customerManager"/>
</create>
</allow>
</dwr>
<dwr>
<allow>
<!-- dwr spring -->
<create creator="new" javascript="JCustomerManager">
<param name="class" value="...XXX.customerManager"/>
</create>
</allow>
</dwr>

Third, you need to use new and spring correctly, and pay attention to the difference between the two.
