这是一个ajax的例子大家好好的看看就是一个鱼眼的效果

if(!dojo._hasResource["dijit.form.NumberSpinner"]){ //_hasResource checks added by build. Do not use _hasResource directly in your code.
dojo._hasResource["dijit.form.NumberSpinner"] = true;
dojo.provide("dijit.form.NumberSpinner");

dojo.require("dijit.form._Spinner");
dojo.require("dijit.form.NumberTextBox");

dojo.declare(
"dijit.form.NumberSpinner",
[dijit.form._Spinner, dijit.form.NumberTextBoxMixin],
{
	// summary:
	// extends NumberTextBox to add up/down arrows for incremental change to the value

	required: true,

	adjust: function(/* Object */ val, /*Number*/ delta){
		// summary: change Number val by the given amount
		var newval = val+delta;
		if(isNaN(val) || isNaN(newval)){ return val; }
		if((typeof this.constraints.max == "number") && (newval > this.constraints.max)){
			newval = this.constraints.max;
		}
		if((typeof this.constraints.min == "number") && (newval < this.constraints.min)){
			newval = this.constraints.min;
		}
		return newval;
	}
});
