最近遇到一个需求要求前端通过接口获取svg中的内容并且填充到svg图中接下来我就记录一下整个实现过程。
第一步找到svg图中每一个需要填充的数据的key值把所有key值交给后端后端会根据key值把value返回给前端如下代码中
g idValue11 fill#00FF00 strokenone font-familyArial font-size29.9999988079072 PB:DisplayPointName9 PB:DisplayTimeStamp9 PB:HorzAlign0 PB:ShowUOMFalse PB:IsMultiStateFalse PB:NumberFormat0.00 PBD:PtTagName\\10.37.169.174\tags.DT_BB02_sab10a0101r PB:PersistString PB:PtTagStatus0 PB:PtTagTime1970/1/1 8:00:00 PB:PtTagValueNo Data PB:Type7 PB:VisibleTrue PB:ScriptingTruerect idValue11_pbTextBoundingRectEl x4387 y782 width142 height40 fillnone stroke-width0/recttext idValue11_pbTextEl x4458 y812 fill#00FF00 strokenone font-familyArial font-size29.9999988079072 text-anchormiddle PBD:PropertyvalueNo Data/text/gPBD:PtTagName“\10.37.169.174\tags.DT_BB02_sab10a0101r” 这个属性代表keytags.DT_BB02_sab10a0101r就是key值
第二步获取数据并填充到对应key中去
querySvgTableById() {let data {plantId: this.powerPlantId,unitId: this.unitId,svgtableId: this.currentSort 1,};querySvgTableById(data).then((res) {this.svgData res.data;this.svgInfo();});},svgInfo() {try {if (this.indexA !
