How to set the input value in a modal dialogue?
提问by Arman
I'm working on 'add a link' functionality. For that I'm using Modal plugin from Twitter Boostrap JS. On the main page there's only the 'link' field to fill, when a user clicks 'add link' button, a modal pops up, and the user sees the complete form to fill 3 fields: link, title, tags. However, I want the link field to be pre-filled with the value from the previous step. It's similar to what happens when you 'save a link' on delicious.com.
我正在研究“添加链接”功能。为此，我使用来自 Twitter Boostrap JS 的 Modal 插件。在主页上只有“链接”字段要填写，当用户单击“添加链接”按钮时，会弹出一个模式，用户会看到完整的表单来填写 3 个字段：链接、标题、标签。但是，我希望使用上一步中的值预先填充链接字段。这与您在美味网站上“保存链接”时发生的情况类似。
Thanks to Joe's help (previous question) I can print the linkURL on the modal dialogue, but it's important that this linkURL is the value of the link field of the form with 3 fields (link, title, tags). Any idea how this can be done?
感谢 Joe 的帮助（上一个问题），我可以在模态对话框上打印 linkURL，但重要的是，此 linkURL 是具有 3 个字段（链接、标题、标签）的表单的链接字段的值。知道如何做到这一点吗？
