我有一个数字输入框的功能,旁边有+
和-
按钮,并复制我使用的shopify
主题中的代码。但该功能只显示一次。但我需要那些适用于所有产品的产品。
(function ($) {
$.fn.bootstrapNumber = function (options) {
var settings = $.extend({
upClass: 'default',
downClass: 'default',
center: true
}, options);
return this.each(function (e) {
var self = $(this);
var clone = self.clone();
var min = self.attr('min');
var max = self.attr('max');
function setText(n) {
if ((min && n < min) || (max && n > max)) {
return false;
}
clone.focus().val(n);
return true;
}
var group = $("<div class='input-group'></div>");
var down = $("<button type='button'>-</button>").attr('class', 'btn btn-' + settings.downClass).click(function () {
setText(parseInt(clone.val()) - 1);
});
var up = $("<button type='button'>+</button>").attr('class', 'btn btn-' + settings.upClass).click(function () {
setText(parseInt(clone.val()) + 1);
});
$("<span class='input-group-btn'></span>").append(down).appendTo(group);
clone.appendTo(group);
if (clone) {
clone.css('text-align', 'center');
}
$("<span class='input-group-btn'></span>").append(up).appendTo(group);
// remove spins from original
clone.prop('type', 'text').keydown(function (e) {
if ($.inArray(e.keyCode, [46, 8, 9, 27, 13, 110, 190]) !== -1 ||
(e.keyCode == 65 && e.ctrlKey === true) ||
(e.keyCode >= 35 && e.keyCode <= 39)) {
return;
}
if ((e.shiftKey || (e.keyCode < 48 || e.keyCode > 57)) && (e.keyCode < 96 || e.keyCode > 105)) {
e.preventDefault();
}
var c = String.fromCharCode(e.which);
var n = parseInt(clone.val() + c);
//if ((min && n < min) || (max && n > max)) {
// e.preventDefault();
//}
});
clone.prop('type', 'text').blur(function (e) {
var c = String.fromCharCode(e.which);
var n = parseInt(clone.val() + c);
if ((min && n < min)) {
setText(min);
}
else if (max && n > max) {
setText(max);
}
});
self.replaceWith(group);
});
};
}(jQuery));
