bootstrap和elementUI真的会冲突
前两天，做了一个支持markdown的功能： http://www.cnblogs.com/XHappyness/p/8097756.html
后面发现预览效果某些标签需要bootstrap的支持才能显出相关的样式，于是乎 npm bootstrap；并在此页面的.ts文件中 import 'bootstrap/dist/css/bootstrap.min.css'，本以为只在改页面引入并不会影响全局样式，然并卵！！
解决办法：将预览地方的div换成iframe
.vue
<div class="marked">
<el-tabs v-model="tastDtailType" @tab-click="changeTab" class="markdown-tabs">
<el-tab-pane label="Write" name="write">
<el-input type="textarea" placeholder="请输入备注" v-model="task.description" :autosize="{minRows: 2, maxRows:30}" class="none-border"></el-input>
</el-tab-pane>
<el-tab-pane label="Preview" name="preview">
<iframe runat="server" frame marginwidth="0" marginheight="0" scrolling="no" allowtransparency="yes"></iframe>
<!-- <div >-->
</el-tab-pane>
</el-tabs>
</div>.css
/* markdown格式 */
.marked {
min-height: 120px;
padding:10px;
border-radius: 4px;
border: 1px solid #bfcbd9;
&:hover {
border-color: #8391a5!important;
}
& #tast-dtail-preview {
margin-left: 7px;
}
}.ts
//任务详情markd是预览还是书写
changeTab(tastDtailType) {
this.tastDtailType = tastDtailType.name;
if (tastDtailType.name === 'preview' && this.task.description != '') {
let tastDtailPreview = Marked(this.task.description);
let iframe = document.querySelector('#tast-dtail-preview') as HTMLIFrameElement;
iframe.contentDocument.body.innerHTML = '<head><link href="http://crowdsourcing.gridsumdissector.com/bootstrap-3.3.7-dist/css/bootstrap.min.css" rel="stylesheet"></head>' + tastDtailPreview;
}
}方法也是笨拙而巧妙，感谢同事帮忙挖坟。。。。
新坑：不滚动的话，内容不能全部显示，目前还没研究怎么是iframe自动高度，于是乎还是滚吧....
//任务详情markd是预览还是书写
changeTab(tastDtailType) {
this.tastDtailType = tastDtailType.name;
if (tastDtailType.name === 'preview') {
let tastDtailPreview = Marked(this.task.description);
let iframe = document.querySelector('#tast-dtail-preview') as HTMLIFrameElement;
iframe.contentDocument.body.innerHTML = '<head><link href="http://crowdsourcing.gridsumdissector.com/bootstrap-3.3.7-dist/css/bootstrap.min.css" rel="stylesheet"></head>' + tastDtailPreview;
let height = $('.none-border').height(); //.none-border是左侧书写部分的 let width = $('.none-border').width();
iframe.style.height = height + 'px'; iframe.style.width = width + 'px';
}
}
