在以下代碼中,我想在單擊svg
符號時創建類似按鈕的功能。我無法獲得sPaper
,sPolyFill
和sPolyEmpty
的值。 只要他們返回undefined。在骨幹視圖中獲取snap.svg對象的值
我需要將symbolAnim
函數集成到like
和unlike
函數中。我怎樣才能做到這一點?
var LikeButtonView = BaseButtonView.extend({
template: _.template($('#like-button-test').html()),
sPaper: null,
sPolyFill: null,
sPolyEmpty: null,
initialize: function (options) {
BaseButtonView.prototype.initialize.apply(this, [options]); // inherit from BaseButtonView
this.butn = $("button.heart-icon", this.$el);
this.sPaper = Snap(heartIcon.get(0));
this.sPolyFill = sPaper.select('.symbol-solid');
this.sPolyEmpty = sPaper.select('.symbol-empty');
},
like: function() {
console.log("Like clicked");
if (this.butn.hasClass("isLiked")) {
this.unlike();
} else if (this.butn.hasClass("unliked")){
this.butn.removeClass("unLiked");
this.butn.addClass("isLiked");
this.addBlur();
}
},
unlike: function() {
this.butn.removeClass('isLiked');
this.butn.addClass("unLiked");
this.addBlur();
},
symbolAnim: function(heartIcon, isLiked) {
if (isLiked === false) {
sPolyFill.animate({ transform: 't9,0' }, 300, mina.easeinout);
sPolyEmpty.animate({ transform: 't-9,0' }, 300, mina.easeinout);
} else {
sPolyFill.animate({ transform: 't0,0'}, 300, mina.easeinout);
sPolyEmpty.animate({ transform: 't0,0' }, 300, mina.easeinout);
}
}
});
