WPF对某个元素进行淡入淡出

WPF对某个元素进行淡入淡出，例如对 ImagePage 元素进行淡入淡出，代码如下：

淡入

daV = new DoubleAnimation(0, 1, new Duration(TimeSpan.FromSeconds(1)));
this.ImagePage.BeginAnimation(UIElement.OpacityProperty, daV);

淡出

DoubleAnimation daV = new DoubleAnimation(1, 0, new Duration(TimeSpan.FromSeconds(1)));
this.ImagePage.BeginAnimation(UIElement.OpacityProperty, daV);

electron中使用jquery

electron中使用jquery：

<!-- Insert this line above script imports  -->
<script>if (typeof module === 'object') {window.module = module; module = undefined;}</script>
<!-- normal script imports etc  -->
<script src="js/jquery.min.js"></script>       
<!-- Insert this line after script imports -->
<script>if (window.module) module = window.module;</script>

<script>   
    $(function(){
        var winHeight = document.documentElement.clientHeight;
        var winWidth = document.documentElement.clientWidth;
        $('.wrapper').css('width', winWidth);
    });
</script>
