It doesn’t seem right for you to be like this, bro. . .

<form ><input type="text" name="cu" id="cu" /><input type="submit" name="Submit" value="提交" onSubmit="showCustomer(document.getElementById('cu').value)" /></form>

test.html?cu=&Submit=�ύ
After you submitted like this, the browser actually brought out the parameters at the end. I thought Submit via ajax without refreshing the page to display data?

Sorry, the input element does not have an onsubmit event. In alert(e), where to write your ajax code
