The image is not displayed when extjs generates a tree.

 

Method 1:

This problem is exposed without the Internet connection of the system.

Because extjs always accesses the s.gif image file http://extjs.com/s.gif by default when generating a tree. The navigation image of the Tree node cannot be displayed without network connection. The right-click attribute shows that it is http://extjs.com/s.gif. After searching, we can find that the s.gif is defined in the ext-base.js file: Blank_image_url: "http:/" + "/extjs.com/s.gif" And extjs examplesProgramIs with this s.gif image file. Modify the ext-base.js: Blank_image_url: "../images/default/s.gif" // find the image path based on the directory structure 2nd methods: In the project to create a general JS file JS write Ext. blank_image_url = "../ext-3.0.0/resources/images/default/s.gif "; It will be OK in reference.
