js 正则去除一段html里  img标签里的style，添加图片自适应 max-width:100%

convert () {

let htmlText = '<img style="border: 0px; width: 537px; display: block;">'

let str = htmlText.replace(/<img[^>]*>/gi, function (match, capture) {

return match.replace(/style\s*?=\s*?([‘"])[\s\S]*?\1/ig, 'style="max-width:100%;height:auto;"')

})

return str

},
