jQuery验证成功显示gif加载器

标签： javascript jquery html jquery-validate loader

我在其中一个表单中使用了jQuery验证插件。验证规则工作正常。

但我的问题是如果验证成功，点击提交按钮后显示gif loader。

有人可以指出我如何使其发挥作用的正确方向吗？

$( "#myform" ).validate({
  rules: {
    fullname: {
      required: true
    },
    mobile:{
    	required:true,
    	minlength: 10,
    	number:true
    },
    email:{
    	required:true,
    	email:true
    }
  },
  messages: {
	    fullname: {
	        required: "Please enter your name"
	    },
	    mobile:{
	    	required: "Please enter your mobile number",
	    	minlength:"Minumum length 10 digits"
	    },
	    email:{
	    	required: "Please enter your email-id",
	    	email: "Invalid email-id"
	    }
	}
});
.gif-loader
{
  display:none;
}

使用此fiddle

您需要为此添加提交处理程序... 

submitHandler: function() { $(".gif-loader").show(); }


$( "#myform" ).validate({
  rules: {
    fullname: {
      required: true
    },
    mobile:{
    	required:true,
    	minlength: 10,
    	number:true
    },
    email:{
    	required:true,
    	email:true
    }
  },
  messages: {
	    fullname: {
	        required: "Please enter your name"
	    },
	    mobile:{
	    	required: "Please enter your mobile number",
	    	minlength:"Minumum length 10 digits"
	    },
	    email:{
	    	required: "Please enter your email-id",
	    	email: "Invalid email-id"
	    }
	},
  submitHandler: function() { $(".gif-loader").show(); $('#myform').submit();}
});
.gif-loader
{
  display:none;
}

您是否尝试过绑定提交事件？插件中有一个submitHandler

要提交，请添加$('#myform').submit()。

修改

而不是我将通过Ajax发送的提交事件，如

submitHandler: function() {
    $('.gif-loader').show();

    $.post("insert.php", $("#myform").serialize(), function(data) {
        alert(data);

        $('.gif-loader').hide();
    });
}

但是，在这种情况下，您可能需要更改insert.php的工作方式。

＆＃13;
＆＃13; 
$( "#myform" ).validate({
  //this bit is new.
  submitHandler: function() {
     $('.gif-loader').show();
  },
  rules: {
    fullname: {
      required: true
    },
    mobile:{
    	required:true,
    	minlength: 10,
    	number:true
    },
    email:{
    	required:true,
    	email:true
    }
  },
  messages: {
	    fullname: {
	        required: "Please enter your name"
	    },
	    mobile:{
	    	required: "Please enter your mobile number",
	    	minlength:"Minumum length 10 digits"
	    },
	    email:{
	    	required: "Please enter your email-id",
	    	email: "Invalid email-id"
	    }
	}
});
＆＃13; 
.gif-loader
{
  display:none;
}
