Dojo/dijit script library treeview loading
The dojo api doesn't seem to load on my system (IE 8, Windows 7 with IIS 7.5). I try to test these examples by linking to the dojo api like this
<script src="http://ajax.googleapis.com/ajax/libs/dojo/1.6.1/dojo/dojo.xd.js"></script>
<script type="text/javascript">
dojo.require("dojo.lang.*");
dojo.require("dojo.widget.Tree");
</script>
I also downloaded the library to link to it directly like this.
<script type="text/javascript" src="dojo.js">/*_*/</script>
<script type="text/javascript">
dojo.require("dojo.lang.*");
dojo.require("dojo.widget.Tree");
</script>
But got the same result. The library scripts don't load the treeview. Are there issues with IE8, Windows 7 or IIS 7.5 for the d开发者_如何学Pythonojo libary 1.6.1?
Do you know of a treeview with this functionality: MySQL database support, context menu, add/delete node, hyperlink in tree support?
Thanks.

You need to wrap the dojo.require calls in the dojo.addOnLoad function. This is required when using Dojo cross-domain build.
See more at http://dojotoolkit.org/reference-guide/quickstart/cross-domain.html
dojo.addOnLoad(function() {
dojo.require("dojo.lang.*");
dojo.require("dojo.widget.Tree");
});
加载中,请稍侯......
