我想知道如何使用http://circletype.labwire.ca/#fitText制作更多设计我是成功制作一个但是就是它只是制作一个圆圈我不能让更多的设计出现问题我的代码可以有人请救命？我怎样才能制作楔形文字和＃34;摆动＆＃34;文本最后一件事我还想知道如何制作螺旋文本，如果有人知道这些将是一个很大的帮助

答案 0 :(得分：1)
我的猜测是你的问题是这个代码：
$("#demo1").click(function(){
$('.changeMe').circleType("fitText:true", $(this).attr('radius: 180'));
});
您没有与此代码匹配的正确div。我将在一分钟内回到这一点，但首先你应该知道，通常一个人不会直接进入并编辑一个库。我的建议是，您可以在自己独立的<script>标记内使用代码。
所以也许在你加载完你的库之后：
<script>
$("#fs").change(function() {
//alert($(this).val());
$('.changeMe').css("font-family", $(this).val());
});
$("#size").change(function() {
$('.changeMe').css("font-size", $(this).val() + "px");
});
$("#demo1").click(function(){
$('.changeMe').circleType("fitText:true", $(this).attr('radius: 180'));
});
</script>
然后你只需修改HTML就可以得到一个而不是按钮的demo1 div：
<div id="demo1">Here is some text I would like to see in a different shape.</div>
此代码可能喜欢针对常规的旧HTML文本而不是按钮运行。
希望这有帮助！
更新：我摆脱了冗余库并简化了代码。此示例应放在HTML文档中的<body>标记之间。单击每一行以查看其运行情况。我还将样式表移动到文档<head>标记中。
<div id="demo1">Here is some text I would like to see in a different shape.</div>
<div id="demo2">Here is some text I would like to see in a different shape.</div>
