我有七个复选框,如下所示:
$.validator.addMethod("contactpersonen-email", function(value, element) {
var parentForm = $(element).closest('form');
var timeRepeated = 0;
if (value != '') {
$(parentForm.find(':text')).each(function () {
if ($(this).val() === value) {
timeRepeated++;
}
});
}
var ok = timeRepeated === 1 || timeRepeated === 0;
if(!ok) alert('Emaild adres bestaat al');
return ok;
}, "Email adres bestaat al");
我有一个用于检查重复电子邮件的javascript函数,如下所示:
<input type="checkbox" class="input-text" value="Y" name="contactpersonen_canseestock_0" id="contactpersonen_canseestock_0"></input>
<label class="checkbox" for="contactpersonen_canseestock_0">Mag gderen afhalen</label>
但现在只检查此复选框:
$.validator.addMethod("contactpersonen-email", function(value, element) {
var parentForm = $(element).closest('form');
var timeRepeated = 0;
if (value != '') {
$(parentForm.find(':text')).each(function () {
if ($(this).val() === value) {
timeRepeated++;
}
});
}
//
$("#contactpersonen_canseestock_0").attr('checked', true);
//Alleen een is checked en dat is Mag gderen afhalen
if ($("#contactpersonen_canseestock_0").is(":checked") && $('#formid :checkbox:checked').length == 1) {
alert("checked");
} else {
// any other check box is checked or none
alert("other combination");
}
//
var ok = timeRepeated === 1 || timeRepeated === 0;
if(!ok) alert('Emaild adres bestaat al');
return ok;
}, "Email adres bestaat al");
然后是必须跳过电子邮件重复功能
但最简单的检查方法是什么?或者您必须检查是否未选中其他每个复选框?
谢谢
这是一个清晰的屏幕截图:
Oke,但如果我这样做的话:
$.validator.addMethod("contactpersonen-email", function(value, element) {
if($("#contactpersonen_canseestock_0").is(':checked')) {
console.log('email is nice');
var parentForm = $(element).closest('form');
var timeRepeated = 0;
if (value != '') {
$(parentForm.find(':text')).each(function () {
if ($(this).val() === value) {
timeRepeated++;
}
});
}
var ok = timeRepeated === 1 || timeRepeated === 0;
if(!ok) alert('Emaild adres bestaat al');
return ok;
}else{
console.log('jkshdfkjsdhf');
return;
}}, "email bestaat al" )
仅用于:选中任何其他复选框或无
见图片: enter image description here
如果我这样试试:
$.validator.addMethod("contactpersonen-email", function(value, element) {
var parentForm = $(element).closest('form');
var timeRepeated = 0;
if (value != '') {
$(parentForm.find(':text')).each(function () {
if ($(this).val() === value) {
timeRepeated++;
}
});
}
//
//
var ok = timeRepeated === 1 || timeRepeated === 0;
$("#contactpersonen_canseestock_0").attr('checked', true);
//Alleen een is checked en dat is Mag gderen afhalen
if ($("#contactpersonen_canseestock_0").is(":checked") && $('#formid :checkbox:checked').length == 1) {
console.log("checked");
return;
} else {
if(!ok) alert('Emaild adres bestaat al');
return ok;
// any other check box is checked or none
console.log("other combination");
}
//if(!ok) alert('Emaild adres bestaat al');
//return ok;
}, "Email adres");
它不起作用。见图像:
OKE。我现在就这样:
console.log("checked");
所以我看到它来了:
}, "Email adres");
。但它也来了:
contactpersonen_email1:{
required:true,
email:true
},
不必是什么。
也许它即将到来,因为我在文件中有以上内容:
if ($("#contactpersonen_canseestock_0").is(":checked") && $('#formid :checkbox:checked').length == 1) {
console.log("checked");
return;
} else {
if(!ok) alert('Emaild adres bestaat al');
console.log('not checked');
return ok;
// any other check box is checked or none
console.log("other combination");
}
return;
//if(!ok) alert('Emaild adres bestaat al');
//return ok;
});
但如果选中第一个复选框,则不需要使用。
谢谢
如果这样做的话:
}); then I will get this warning:
所以这个:
$('#formid :checkbox').change(function() {
//only one is checked and that is Mag gderen afhalen
if ($("#contactpersonen_canseestock_0").is(":checked") && $('#formid :checkbox:checked').length == 1) {
console.log("only Mag gderen afhalen checked");
} else {
// any other check box is checked or none
console.log("other combination");
}});
警告:没有为contactpersonen_email定义消息
如何组合此方法:
$.validator.addMethod("contactpersonen-email", function(value, element) {
var parentForm = $(element).closest('form');
var timeRepeated = 0;
if (value != '') {
$(parentForm.find(':text')).each(function () {
if ($(this).val() === value) {
timeRepeated++;
}
});
}
var ok = timeRepeated === 1 || timeRepeated === 0;
if(!ok) alert('Emaild adres bestaat al');
return ok;
}, "Email adres bestaat al");
用这种方法:

我认为你的问题是关于检查了多少,而不是检查了某一个..
$("input[type='checkbox']:checked").length
会为您提供已选中复选框的数量..
答案 1 :(得分:1)
你不需要jQuery ......
//To count how many are checked/ticked
document.querySelectorAll('input[type="checkbox"]:checked').length
//To check a specific checkbox...
if(document.getElementById('contactpersonen_canseestock_0').checked) {
// It is checked, do something
} else {
// Not checked, do something else
}
但是如果你想要jQuery ......
if($("#contactpersonen_canseestock_0").is(':checked')){
// It is checked, do something
} else {
// Not checked, do something else
}

$.validator.addMethod("contactpersonen-email", function(value, element) {
if($("#contactpersonen_canseestock_0").is(':checked')) {
var parentForm = $(element).closest('form');
var timeRepeated = 0;
if (value != '') {
$(parentForm.find(':text')).each(function () {
if ($(this).val() === value) {

您可以按ID检查特定检查,然后通过表单ID查找其他内容。查看此fiddle或附加的代码段。
$('#formid :checkbox').change(function() {
//only one is checked and that is Mag gderen afhalen
if ($("#contactpersonen_canseestock_0").is(":checked") && $('#formid :checkbox:checked').length == 1) {
console.log("only Mag gderen afhalen checked");
} else {
// any other check box is checked or none
console.log("other combination");
}});

答案 3 :(得分:0)
你可能只是喜欢;
document.querySelectorAll("[type=checkbox]:checked").length === 1
更确切地说,在你的情况下:
document.querySelector("div.contact-label.span11.rights")
.querySelectorAll("[type=checkbox]:checked").length === 1 ? doThis()
: doThat();
答案 4 :(得分:-1)
因为您只想检查是否选中了特定复选框,所以使用一点点jQuery很容易...使用条件和:选中,如下所示:
if($("#contactpersonen_canseestock_0").is(":checked")){
//Skip Function
}
else{
doThisFunction();
}
希望它有所帮助。问候:)
