(vue)Vue前台警告You may have an infinite update loop in watcher with expression

(vue)Vue前台警告You may have an infinite update loop in watcher with expression

原因：循环的数组设置了全局（和我的特殊数组有关）

修改前：

    //遍历标签changeCompare(val, keyword) { this.textList.forEach((item1) => {this.color = item1.color; //区别this.contentTest = item1.content; //区别this.contentTest.forEach((item) => {keyword = item;val = val + "";if (val.indexOf(item) !== -1 && item !== "") {val = val.replace(new RegExp(item, "g"),`<font color='#000' style="background-color: ${this.color};border-radius: 5px;padding: 2px 4px; margin:2px;">${item}</font>`);}});});return val; },

修改后：

    //遍历标签changeCompare(val, keyword) { this.textList.forEach((item1) => { var color = item1.color; //区别var contentTest = item1.content; //区别contentTest.forEach((item) => {keyword = item;val = val + "";if (val.indexOf(item) !== -1 && item !== "") {val = val.replace(new RegExp(item, "g"),`<font color='#000' style="background-color: ${color};border-radius: 5px;padding: 2px 4px; margin:2px;">${item}</font>`);}});});return val; },
