问题 I have problems setting load mask on panel properly. After click on a button the new tree store is being generated (localy) and it takes quite some time. The load mask shows for a millisecond only after (i think) the whole function evaluates. In my code console.log(0) and console.log(1) shows after the whole function processes, the button alone freezes for couple of seconds then unfreezes and after that console shows 0 and 1 . What is the proper way to handle this kind of situations. Here is

问题 With ExtJS 3.x, I was able to use the "fields" property of a Store, but it seems with ExtJS 4 I have to absolutely use a Model. It's fine, but in my case, it's not a static Model, and I need to define the fields on the fly and sometimes to change them. I could re-create a Model, but I need to use a different name as it's apparently not possible to modify an exisiting Model, neither delete it. If I try to use Ext.regModel with the same name, ExtJS crashes. Thanks for your help! 回答1: 4.1 UPDATE

问题 I want to create custom ExtJS form field components using other ExtJS components in it (e.g. TreePanel). How can I do it most easily? I've read docs of Ext.form.field.Base but I don't want to define field body by fieldSubTpl . I just want to write code which creates ExtJS components and maybe some other code which gets and sets values. Update: Summarized purposes are the followings: This new component should fit in the form GUI as a field. It should have label and the same alignment (label,

问题 In ExtJs, there are many options to filter a grid. There are two nice examples in the documentation, like referenced in this question. Remote filtering Local filtering However, having the filter hidden in the default dropdown menu of Ext.ux.grid.FiltersFeature looks really awkward for me. A good ergonomic choice would to create search fields in the column headers, like @Ctacus shows in his question. How can this be achieved ? 回答1: After quite much research through the sparse documentation,

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 3 years ago . I need to implement CSRF attack prevention using token in application that uses ajax post requests (ExtJs library) to Struts actions. How can I implement token generation and validation in such case? 回答1: In ExtJS you can use this: Ext.Ajax.setDefaultHeaders({ token: 'xyz' }) This

问题 I am working with ASP.NET MVC and have a view page with a simple text box and button to accompany it. I want AJAX to submit the form when the user clicks the search button. The response (search results) will be returned and displayed in a content div on the same page. I have done this successfully with JQuery, but I need the same functionality in ExtJS. Here is the JQuery (the form id is #helpsearchbox and #helpcontent is the id of the content div I want the results to be loaded into): $
