IE7的下拉重置问题在FireFox和Chrome上运行正常(Dropdown reset issues with IE7 works fine on FireFox and Chrome)

 Hello Stackoverflow我有一个简单的表单验证逻辑，由于某种原因似乎不适用于IE7。 
 
 基本上我有两个下拉框和一个输入框。 当第一个下拉框状态更改另一个下拉列表并且输入框清除时。 
 
 目前这种逻辑似乎适用于FF，Chrome但不适用于IE7。 此外，清除输入框也可以在IE上按预期工作。 
 
$('#names').change(function(){
    $('#rate').val("0");
    $('#amount').val("");
});
 
 任何帮助将不胜感激。 

Hello Stackoverflow I have a simple form validation logic that doesn't seem to work on IE7 for some reason.
 
Basically I have two dropdown boxes and an input box. When the first dropdown box state changes the other dropdown and inputbox clears.
 
Current this logic seem to work on FF, Chrome but not IE7. Also the clearing of the input box works as expected on IE as well.
 
$('#names').change(function(){
    $('#rate').val("0");
    $('#amount').val("");
});
 
Any helps would be greatly appreciated.
