にハードコーディングすることなく、私はへの修正を見つけましたjqBootstrapValidationの複数選択検証。
私はdocumentationを見ました...そして、これは私がそれを働かせる方法です。
select
のためのHTML:
<select id="food"
class="form-control selectpicker"
multiple title="Choose at least 2"
required
data-validation-required-message="Required"
data-validation-multiple-message="Select at least two fruits.";
>
機能:
$(function() {
// Define the select variables to use.
var selectID = "#food";
var selectMinimum = 2;
var selectedValues = [];
var selectSeparator = "-SEP-"; // This separator will be usefull on PHP side
// to explode values from $_POST['interests']
// Get the selected values
$("#food").on("mouseup",function(){
selectedValues = $(this).val();
selectedValues = selectedValues.join(selectSeparator);
$("#interests").val(selectedValues);
});
// Custom submit
function customSubmit(event){
// Display selections in console.
console.log(selectedValues);
// Check if there is less selections than selectMinimum in selectID
if(selectedValues.length<selectMinimum){
event.preventDefault();
console.log("Missing fruit.");
// Do BootStrap's job here...
$(selectID).attr("aria-invalid",true).focus();
$(".control-group").removeClass("success").addClass("warning");
$(".help-block").html("<ul role='alert'><li>"+$(selectID).data('validation-multiple-message')+"</li></ul>");
// If more than selectMinimum in selectID
// Since only the last selection is sent...
// Again, do BootStrap's job!
}else{
event.preventDefault();
// Get ALL the form's data
var formData = $(".form-horizontal").serialize();
console.log(formData);
// Now post it.
$.post("#", formData,function(data) {
// That is a custom confirm for this CodePen...
// You can do better.
$("body")
.empty()
.css({"padding":"10px","text-align":"center"})
.html("<h1>DATA SENT:</h1><i>using jQuery $.post()</i><br><br><h3>"+formData+"</h3>");
});
}
}
// jqBootstrapValidation initialisation
$(".form-horizontal").find("input,textarea,select").jqBootstrapValidation({
preventSubmit: true,
submitError: function($form, event, errors){
// Here I do nothing, but you could do something like display
// the error messages to the user, log, etc.
},
submitSuccess: function($form, event){
customSubmit(event);
},
filter: function() {
return $(this).is(":visible")
}
});
});
はCodePenでそれを参照してください。
