我正在寻找构建一个脚本,在表单提交或选择更改时打开一个微调器。
我想使用spin.js,(这是开发人员的一个工作示例):
var opts = {
lines: 11, // The number of lines to draw
length: 15, // The length of each line
width: 10, // The line thickness
radius: 30, // The radius of the inner circle
corners: 1, // Corner roundness (0..1)
rotate: 0, // The rotation offset
direction: 1, // 1: clockwise, -1: counterclockwise
color: '#000', // #rgb or #rrggbb
speed: 0.6, // Rounds per second
trail: 60, // Afterglow percentage
shadow: false, // Whether to render a shadow
hwaccel: false, // Whether to use hardware acceleration
className: 'spinner', // The CSS class to assign to the spinner
zIndex: 2e9, // The z-index (defaults to 2000000000)
top: 'auto', // Top position relative to parent in px
left: 'auto' // Left position relative to parent in px
};
var spinner = null;
var spinner_div = 0;
$(document).ready(function() {
spinner_div = $('#spinner').get(0);
$("#btn-spin").click(function(e) {
e.preventDefault();
if(spinner == null) {
spinner = new Spinner(opts).spin(spinner_div);
} else {
spinner.spin(spinner_div);
}
});
});
所以...当我点击我的提交按钮
<input id="btn-spin" type="submit" name="next" value="Continua" class="button-big"/>
或当我在选择
上更改值时 <select name="billing_country" onChange="this.form.submit();">
{billing_country_options}
</select>
我想:
非常感谢

假设您已正确初始化了微调器,我们可以使用jQuery监听表单提交或选择更改事件,并避免使用内联JS。对于<select>
,只需删除内联JS。
$(function() {
// Remember to use 'var'
var spinner_div = $('#spinner').get(0),
spinner,
opts = {
// Opts go here
},
showSpinner = function() {
// Add 'lightbox-is-open' and 'lightbox-is-fixed' classes to HTML
$('html').addClass('lightbox-is-open lightbox-is-fixed');
// Remove 'hidden' class from '.glasspane'
$('.glasspane').removeClass('hidden');
// Show spinner
if(spinner == null) {
spinner = new Spinner(opts).spin(spinner_div);
} else {
spinner.spin(spinner_div);
}
// Submit form after 500ms
var timer = window.setTimeout(function() {
$('form').submit();
}, 500);
};
// Bind events
$('form').on('submit', function(e) {
e.preventDefault();
showSpinner();
});
$('#btn-spin').on('click', function(e) {
e.preventDefault();
showSpinner();
});
$('select').on('change', showSpinner);
});
