SVG 图标只变形一次，不会变形回来

Question

我正在使用 SVG Morpheus 根据用户点击来回变换两个图标。我有两个问题。

1) The first icon initially doesn't show up. I realize this is because I put a display:none on there but that's how it was shown in the demo. Am I supposed to take off the display:none styling for the initial icon?

2) When I first click on the 'Get in Touch' text, the icon morphs fine. However, when I click the text (now 'Projects') again, the icon doesn't morph back.

我已经为工作图标创建了两个函数来变身为邮件图标，反之亦然。另外，如果有更有效的方法将这两个功能合并为一个功能，我会洗耳恭听。

我哪里做错了？

function morphMail() {
    var myIcons = new SVGMorpheus('#iconset');

$('#contact-button').click(function (e) {
    e.preventDefault();

    if (c++ % 2 == 0) {

        $(this).addClass('project-button').text('Projects');

    } else {

        $(this).removeClass('project-button').text('Get in touch');
        morphWork();
    }
});

Answer 1

想通了。猜猜我只能使用 var myIcons = new SVGMorpheus('#iconset'); 一次。这是最终结果：http://jsfiddle.net/o8u9225q/6/

制作你的第一个图标display:block;。而不是一键调用这两个函数，使它们成为不同的 click 函数。

要获取邮件图标，您必须更改邮件功能。

 function morphWork() {
        var myIcons = new SVGMorpheus('#iconset');
        myIcons.to('mail');
    };

    function morphMail() {
        var myIcons = new SVGMorpheus('#iconset');
        myIcons.to('work');
    };

至此

   function morphWork() {
        var myIcons = new SVGMorpheus('#iconset');
        myIcons.to('work');
    };

    function morphMail() {
        var myIcons = new SVGMorpheus('#iconset');
        myIcons.to('mail');
    };
