我正在为toastr.js寻找解决方案＆＃34;错误＆＃34;导致网页（如果向下滚动）在显示新的toastr时再次跳起
GitHub page containing the script
我试图将顶部更改为自动，但这不是一个可接受的参数，因为当时没有任何内容显示。
目前还没有办法让它出现在鼠标的哪个位置？
.toast-top-center {
top: 12px;
margin: 0 auto;
left: 43%;
}
这有调用代码：
<p><span style="font-family:'Roboto','One Open Sans', 'Helvetica Neue', Helvetica, sans-serif;color:rgb(253,253,255); font-size:16px ">
<a href="#" style="color: rgb(255,0,0,0)" onclick="playclip()">xxxxxxxxxxxxx </a>
</span></p>
这是功能代码：
<script type='text/javascript'> function playclip() {
toastr.options = {
"debug": false,
"positionClass": "toast-top-center",
"onclick": null,
"fadeIn": 800,
"fadeOut": 1000,
"timeOut": 5000,
"extendedTimeOut": 1000
}
toastr["error"]("This link is pointing to a page that hasn't been written yet,</ br> sorry for the inconvenience?"); } </script>
这是脚本本身： / *

答案 0 :(得分：1)
将您的代码更改为：
<a href="#" style="color: rgb(255,0,0,0)" onclick="playclip(); return false;" >xxxxxxxxxxxxx </a>
但是，我会重新考虑使用这种类型的javascript调用。看一下这个"javascript:void(0);" vs "return false" vs "preventDefault()"
