嵌入式 ruby 语法问题
Embedded ruby syntax issue
我在让这个嵌入式 Ruby 工作时遇到问题:
<%= image_tag "svg/illustrations/non-standard-hero-shape.svg", class: "js-svg-injector", data: {
img_paths: '[
{"targetId": "#SVGNonStandardHeroShapeImg1", "newPath": "<%= image_path(\'cover-photo.jpg\') %>"},
{"targetId": "#SVGNonStandardHeroShapeImg2", "newPath": "<%= image_path(\'cover-photo.jpg\') %>"}
]',
parent: "#SVGNonStandardHeroShape" } %>
对
的两次调用都存在问题
<%= image_path(\'cover-photo.jpg\') %>
错误是:
syntax error, unexpected tIDENTIFIER, expecting '}'
syntax error, unexpected ']', expecting ')'
我强烈建议将此数据构建为纯 ruby 对象,然后将其编码为 JSON。那么你就不用太担心所有的 <%=
标签了。
img_paths: [
{
targetId: "#SVGNonStandardHeroShapeImg1",
newPath: image_path('cover-photo.jpg')
},
{
targetId: "#SVGNonStandardHeroShapeImg2",
newPath: image_path('cover-photo.jpg')
},
].to_json
