jQuery 仅使用提交按钮验证检查表单

如何解决jQuery 仅使用提交按钮验证检查表单

我有一个问题，我已经两天没有解决了。我有一个表格。我想在发送之前用 jQuery Validate 检查这个表单。但我真正想要的是它只在我点击提交按钮时检查。正如您在示例中看到的那样，每次我对输入进行更改时都会打开弹出窗口。我该怎么办？

$("#intro_send_form").on('click',function(){
    $('#sendclip_form').validate({
        ignore: [],focusInvalid: false,rules: {
            mail: {
                required: true
            },password: {
                required: true
            }
        },messages: {
            mail: {
                required: "Mail input cannot be the empty.",},password: {
                required: "Password input cannot be the empty.",showErrors: function(errorMap,errorList) {
            
            var summary = "Your form contains " + this.numberOfInvalids() + " errors,see details above.</br>";
            //$(".form-message").html("Your form contains " + this.numberOfInvalids() + " errors,see details above.");
            $('#copyMessage').addClass('alert-open');
            $.each(errorList,function() {
                summary += "<span class='error_entrys'>" + this.message + "</span>";
            });
            $("#copyMessage").html(summary);
            setTimeout(function(){
                $('#copyMessage').removeClass('alert-open');
            },3000);
        
        },submitHandler: function(form) {
            var $form = $(form);
            var $inputs = $form.find("input,select,button,textarea");
            var serializedData = $form.serialize();
            // ajax something
        }
    });
});

解决方法

您必须在显示错误后重置表单。

见下面的片段。

var err = 0;

$("#intro_send_form").on('click',function(e){
    
    var form = $('#sendclip_form').validate({
        ignore: [],focusInvalid: false,onkeyup: false,onclick: false,onfocusout: false,rules: {
            mail: {
                required: true
            },password: {
                required: true
            }
        },messages: {
            mail: {
                required: "Mail input cannot be the empty.",},password: {
                required: "Password input cannot be the empty.",showErrors: function(errorMap,errorList) {
            err = this.numberOfInvalids();
            if(err != 0){
              var summary = "Your form contains " + this.numberOfInvalids() + " errors,see details above.</br>";
            //$(".form-message").html("Your form contains " + this.numberOfInvalids() + " errors,see details above.");
            $('#copyMessage').addClass('alert-open');
            $.each(errorList,function() {
                summary += "<span class='error_entrys'>" + this.message + "</span>";
            });
            $("#copyMessage").html(summary);
            setTimeout(function(){
                $('#copyMessage').removeClass('alert-open');
            },3000);
            
        
        }
        form.resetForm();
            },submitHandler: function(form) {
            var $form = $(form);
            var $inputs = $form.find("input,select,button,textarea");
