关于form表单中button按钮自动提交问题

//错误代码:
<Button id="btnSubmit" name="btnSubmit" class="btn btn-primary" >确认</Button>

$("#btnSubmit").click(function(){
    $(‘#formSave‘).ajaxSubmit(function(data) {
    if(data.code == 0){
         $.alert({
            title: ‘提示!‘,
            content: ‘添加成功!‘
        }); 
    }
    });
});

//改正后代码:
<input id="btnSubmit" type="button" class="btn btn-primary" value="确认"/>
