问题描述
在我的Rails应用程序中，我尝试使用jquery-tokeninput.我一切正常-json响应和所有-但是当在tokenized字段中键入任何内容时脚本出错，抱怨:
In my rails application I am trying to use jquery-tokeninput. I have everything working - json response and all - but the script errors out when anything is typed into the tokenized field, complaining:
TypeError: term is undefined
--> return term.replace(regexp_special_chars, '\\$&');
同时加载了jQuery和tokeninput脚本.是什么原因造成的?
Both jQuery as well as the tokeninput scripts are loaded. What could cause this?
推荐答案
听起来您可能需要指定propertyToSearch.默认情况下，Tokeninput查找一个名称"字段，但是如果您在json响应中没有该字段，则需要告诉它要查看的内容.例如，如果您的json看起来像这样:
It sounds like you might need to specify propertyToSearch. By default, Tokeninput looks for a "name" field, but if you don't have that field in the json response, you need to tell it what to be looking at. For example, if your json looks like this:
[
{"id":"856","title":"House"},
{"id":"1035","title":"Desperate Housewives"},
...
]
然后，您需要确保包含以下内容:
Then you need to make sure you include this:
$('#tvshow_tokens').tokenInput('/tvshows.json', { propertyToSearch: 'title' });
