我是一个jQuery新手 - 但已设法修改轮盘赌脚本以旋转我正在制作的主页的“饼图”。
效果很好 - 但客户还希望在任一侧添加一个箭头,以便在点击时将饼图前进一个部分 - 顺时针旋转一个箭头,逆时针旋转另一个箭头。
有没有办法指定部分旋转?
非常感谢任何指导!我正试图遇到一个荒谬的截止日期,并且正在努力解决这个问题。
这是页面: http://bluetabby.com/rr/index13.html
到目前为止,这是jQuery代码 - 我需要弄清楚的函数是leftArrow和rightArrow:
$( document ).ready(function() {
window.WHEELOFFORTUNE = {
cache: {},
init: function () {
console.log('controller init...');
var _this = this;
this.cache.wheel = $('.wheel');
this.cache.wheelSpinBtn = $('.wheel');
this.cache.leftArrow = $('.leftarrow');
this.cache.rightArrow = $('.rightarrow');
//mapping is backwards as wheel spins clockwise //1=win
this.cache.wheelMapping = ['Mitzvahs','Galas','Florals','Props','Weddings'].reverse();
this.cache.wheelSpinBtn.on('load', function (e) {
e.preventDefault();
if (!$(this).hasClass('disabled')) _this.spin();
});
this.cache.rightArrow.on('click', function (e) {
e.preventDefault();
if (!$(this).hasClass('disabled')) _this.spin();
});
},
spin: function () {
console.log('spinning wheel');
var _this = this;
//disable spin button while in progress
this.cache.wheelSpinBtn.addClass('disabled');
/*
Wheel has 10 sections.
Each section is 360/10 = 36deg.
*/
var deg = 1000 + Math.round(Math.random() * 1000),
duration = 6000; //optimal 6 secs
_this.cache.wheelPos = deg;
//transition queuing
//ff bug with easeOutBack
this.cache.wheel.transition({
rotate: '0deg'
}, 0).delay(1000)
.transition({
rotate: deg + 'deg'
}, duration, 'easeOutCubic');
//move marker
_this.cache.wheelMarker.transition({
rotate: '-20deg'
}, 0, 'snap');
//just before wheel finish
setTimeout(function () {
//reset marker
_this.cache.wheelMarker.transition({
rotate: '0deg'
}, 300, 'easeOutQuad');
}, duration - 500);
//wheel finish
setTimeout(function () {
// did it win??!?!?!
var spin = _this.cache.wheelPos,
degrees = spin % 360,
percent = (degrees / 360) * 100,
segment = Math.ceil((percent / 5)), //divided by number of segments
win = _this.cache.wheelMapping[segment - 1]; //zero based array
console.log('spin = ' + spin);
console.log('degrees = ' + degrees);
console.log('percent = ' + percent);
console.log('segment = ' + segment);
console.log('win = ' + win);
//re-enable wheel spin
_this.cache.wheelSpinBtn.removeClass('disabled');
}, duration);
},
resetSpin: function () {
this.cache.wheel.transition({
rotate: '0deg'
}, 0);
this.cache.wheelPos = 0;
}
}
window.WHEELOFFORTUNE.init();
});//]]>
感谢您的任何指示!

我查看了你的代码并发现你正在使用transit.js来制作旋转动画。从本质上讲,对象的css(转换"旋转")正在更新一段时间(如jQuery的动画)。
您可以使用旋转和旋转功能(或您喜欢的任何名称)扩展您的幸运物品轮,您可以将其绑定到您将要创建的按键/按钮。您的代码看起来像这样:
WHEELOFFORTUNE.spinright = function() {
// get current degree of wheel and convert to integer
var degree = parseInt( this.cache.wheel.css('rotate'), 10 );
this.cache.wheel.transition( { "rotate": (degree + 73) + "deg" },1000 );
}
WHEELOFFORTUNE.spinleft = function() {
var degree = parseInt( this.cache.wheel.css('rotate'), 10 );
this.cache.wheel.transition( { "rotate": (degree - 73) + "deg" },1000 );
}
然后,您可以将这些函数绑定到按钮或直接在控制台中调用函数:
WHEELOFFORTUNE.spinright()
WHEELOFFORTUNE.spinleft()
注意:73deg看起来与1节的数量有关,但你可能不得不玩这些数字。您可能还想在对象中缓存度数。您可能还需要找到一种方法,以按下每个按钮的每个部分为中心。
干杯!
