uniapp 富文本图片100%显示

下面的这个方法是在百度上找的，但是老是报错，一直没找到原因，索性自己就挨个检查了下，发现在过滤之前需要对传过来的值进行检测，是字符串才能让这个方法执行

filters: {
    formatRichText(html) { //控制小程序中图片大小
        let newContent = ''
            newContent = html.replace(/<img[^>]*>/gi,
            function(match) {
                match = match.replace(/style="[^"]+"/gi, '').replace(/style='[^']+'/gi, '');
                match = match.replace(/width="[^"]+"/gi, '').replace(/width='[^']+'/gi, '');
                match = match.replace(/height="[^"]+"/gi, '').replace(/height='[^']+'/gi, '');
                return match;
            });
            newContent = newContent.replace(/style="[^"]+"/gi,
            function(match) {
                match = match.replace(/width:[^;]+;/gi, 'max-width:100%;').replace(/width:[^;]+;/gi, 'max-width:100%;');
                return match;
            });
            newContent = newContent.replace(/<br[^>]*\/>/gi, '');
            newContent = newContent.replace(/\<img/gi, '<img style="max-width:100%;height:auto;display:inline-block;margin:10rpx auto;"');
            return newContent;

    }
},

以下为完整方法

filters: {
    formatRichText(html) { //控制小程序中图片大小
        let newContent = ''
        if (typeof(html) == 'string') { //检测值为字符串才能进行replace操作
            newContent = html.replace(/<img[^>]*>/gi,
            function(match) {
                match = match.replace(/style="[^"]+"/gi, '').replace(/style='[^']+'/gi, '');
                match = match.replace(/width="[^"]+"/gi, '').replace(/width='[^']+'/gi, '');
                match = match.replace(/height="[^"]+"/gi, '').replace(/height='[^']+'/gi, '');
                return match;
            });
            newContent = newContent.replace(/style="[^"]+"/gi,
            function(match) {
                match = match.replace(/width:[^;]+;/gi, 'max-width:100%;').replace(/width:[^;]+;/gi, 'max-width:100%;');
                return match;
            });
            newContent = newContent.replace(/<br[^>]*\/>/gi, '');
            newContent = newContent.replace(/\<img/gi, '<img style="max-width:100%;height:auto;display:inline-block;margin:10rpx auto;"');
            return newContent;

        }

    }
},
