Html渲染
HtmlViewer
插件通过将一个外部DIV附着在图形控件上,从而改变原有图形的显示方式。允许使用者自己定义HTML通过HTML元素。本示例演示了通过Html来扩展渲染图形,从而获得更加丰富的图形展现。
通常情况下,我们创建的图形控件,如下图所示:
通过HtmlViewer
插件,我们可以使用表现力更强的HTML元素来替换显示的图形,或者结合业务需要,将一些业务数据显示在图形上,如下:
本篇最后提供的示例可以在DDei文档直接预览。
一、HTML渲染
ReplaceDivDemo.vue 渲染模板
<script lang="ts">
export default {name: "replace-div-demo",props: {type: {type: String,default: null},name: {type: String,default: null},matchField:{type: String,default: null},editor:{type:Object,default:null}},mounted() {let field = this.matchField;this.editor.renderViewerIns[this[field]] = this.$refs['divElement']}
};
</script>
<template><div ref="divElement"style="display: flex;flex-direction:column;text-align:center;align-items: center;background: white;color:black;display: none;"><div style="width:100%;display: flex;text-align:center;align-items: center;"><div style="flex:1">代码</div><div style="flex:1">{{ type }}</div></div><div style="width:100%;display: flex;text-align:center;align-items: center;"><div style="flex:1">名称</div><div style="flex:1">{{ name }}</div></div></div>
</template>
demo.vue
<script setup lang="ts">
import DDeiEditorView from "ddei-editor";
