Jquery tokenInput 未预填充 text_field
您好，我有 tokenInput 文档，但不知何故，我的文本字段category_tokens 在编辑时没有预先填充类别。
这是代码片段
<input id="product_category_tokens" type="text" size="30" name="product[category_tokens]" data-pre="[{"created_at":"2010-09-13T03:33:17Z","description":"","id":x,"name":"Kitchen & Dining ","parent_id":xx,"permalink":"kitchen-dining","updated_at":"2011-01-05T11:17:10Z"}]" style="display: none;">
$(function() {
$("#product_category_tokens").tokenInput("/categories.json", {
crossDomain: false,
prePopulate: $('#product_category_tokens').data('pre'),
preventDuplicates: true
});
});
<%= f.text_field :category_tokens, "data-pre" => @product.categories.map(&:attributes).to_json %>
任何指针表示赞赏！
Hi I've tokenInput documentation but somehow my text_field category_tokens is not prepopulated with categories while editing.
Here are code snippets
<input id="product_category_tokens" type="text" size="30" name="product[category_tokens]" data-pre="[{"created_at":"2010-09-13T03:33:17Z","description":"","id":x,"name":"Kitchen & Dining ","parent_id":xx,"permalink":"kitchen-dining","updated_at":"2011-01-05T11:17:10Z"}]" style="display: none;">
$(function() {
$("#product_category_tokens").tokenInput("/categories.json", {
crossDomain: false,
prePopulate: $('#product_category_tokens').data('pre'),
preventDuplicates: true
});
});
<%= f.text_field :category_tokens, "data-pre" => @product.categories.map(&:attributes).to_json %>
Any pointer is appreciated!

也许您可以尝试将
prePopulate更改为$(this).data("pre")。另一个技巧是在 JS 函数和视图中使用字段类而不是 id，因为它在渲染时会发生变化。
希望对您有帮助。
Maybe you can try to change your
prePopulateto$(this).data("pre").Another tip is to use field class instead of id in the JS function and in your view since it changes when rendered.
Hope it help you.
Json 应该返回对象而不是字符串，这会将字符串转换为 Json 对象
Json should return objects not as string this will convert string to Json object
