问题
I am working on my first project with Spring, Spring-JS and DoJo(dijit) and I have two questions bases on the following coding example.
1) How do I check with Dojo (dijit) that the phone number field is the right size and also how do I check that the name field is bigger then 3 and less then 50?
2) As you can see my form has radio buttons which I need to set as required. How do I do that with Dojo (dijit).
Thanks

回答1:
so here is an answer to the radiobutton, with an example:
Spring.addDecoration(new Spring.ElementDecoration({
elementId : 'A',
widgetType : "dijit.form.RadioButton",
widgetModule : "dijit.form.CheckBox",
validate: function (){
if(dojo.query('INPUT[name=type]', 'customer').filter(function(n){return n.checked;}).length > 0){return true;} else {alert('choose a type');return false;}
},
widgetAttrs : ...
}));
now you should be able to do the same with your name field
