markdown 图片自定义渲染，token.attrGet('alt') 获取不到值 #4607
Description
Describe the bug
markdown 图片自定义渲染，token.attrGet('alt') 获取不到值。
md.renderer.rules.image = (tokens, idx, options, env, self) => { const token = tokens[idx]; let alt = token.attrGet('alt'); console.log("alt :"+ alt); let result = self.renderToken(tokens, idx, options); if (alt) { result +=\n } return result; }
这段代码alt的值获取不到。
Reproduction
config.js 的markdown配置中配置如下：
md.renderer.rules.image = (tokens, idx, options, env, self) => { const token = tokens[idx]; let alt = token.attrGet('alt'); console.log("alt :"+ alt); let result = self.renderToken(tokens, idx, options); if (alt) { result +=\n } return result; }
Expected behavior
希望可以取到alt属性值。
