定义四个方法用来转换

	formatColor(str) {
        var _this = this
        const newstr = str.replace(/(rgb\()|(\))/g, '')
        console.log(newstr,"546")
        const arr = newstr.split(',')
        console.log(arr,"546")
        let res = '#'
        for(var val of arr){
            res += _this.fillZero(_this.switchNumToSixteen(parseInt(val)))
        }
        return res
    }
        
    switchNumToSixteen(num) {
        return num.toString(16)
    }


    fillZero(str) {
        if(parseInt(str, 16) < 16) {
            return '0' + str
        }
        return str
    }
    formatStr(str) {
        let _this = this
        return str.replace(/(rgb\().+?(\))/g,function(){
            console.log(arguments[0],"000")
            return _this.formatColor(arguments[0])
        });
    }

用法：

res.info.company_activity = "<p><span style=\\\"\\\\&quot;color:#ff0000\\\\&quot;\\\">12321<span style=\\\"\\\\&quot;color:#000000\\\\&quot;\\\">12313<span style=\\\"\\\\&quot;color:#548dd4\\\\&quot;\\\">12311313<span style=\\\"\\\\&quot;color:#999999\\\\&quot;\\\">123123123<img src=\\\"/upload/ueditor/10012964/140342/style_chat/2021092416284679923.jpg\\\"/></span></span></span></span><br/></p>"

a =  this.formatStr(res.info.company_activity).replace(/\\/g,"");
//其中.replace(/\\/g,"");是为了去除'\\\'
