Question

使用jstree时，下面的代码行会引发链接中提到的异常 http://code.google.com/p/jstree/issues/detail?id=294

**"ui" : { "initially_select" : [ quotedAndCommaSeparated ] }**
**"core" : { "animation" : 0, "initially_open" : [ quotedAndCommaSeparated ] }**

如果我使用如下所示的硬编码值，则无任何问题。

"ui" : { "initially_select" : ['3381','7472','7473','7474','7247','7248','7249','3273','3272'] }

"core" : { "animation" : 0, "initially_open" : [ '3381','7472','7473','7474','7247','7248','7249','3273','3272' ] }

我已经从数组中形成了quotedAndCommaSeparated，它与上面的硬编码值相同。但问题仍未得到解决。请建议。

quotedAndCommaSeparated = '3381','7472','7473','7474','7247','7248','7249','3273','3272'

你的错误是quotedAndCommaSeparated不是一个列表，它只是一个字符串。

您只需在initialSelect列表中添加字符串而不是数字

initiallySelect.push(companyId + "");

然后你可以直接在jstree init

中使用它

"ui" : { "initially_select" : [ initiallySelect ] },

希望有所帮助。

jstree initial_select和initial_open
