extjs

问题 I am writing a test in JMeter for our web app, but there is one page that loads and then makes an Ajax call using extjs libraries to load an additional piece, and I need to know when that piece loads. How should I go about doing this? can JMeter support extjs libraries? What else do I need to know? Searching the internet I've found some ajax and JMeter resources and a few extjs and JMeter sources, but I have yet to find all three in one place. Thanks in advance! 回答1: JMeter's HTTP request

问题 I want to render a split button into a column in a grid to perform actions on each row. I can't seem to figure out how to build a custom cell renderer that will accomplish this. Each cell will have the exact same split button, but will act on the id of the row the split button is in. 回答1: You need to setup a custom renderer for the column, have a look at this example: http://techmix.net/blog/2010/11/25/add-button-to-extjs-gridpanel-cell-using-renderer/ 来源： https://stackoverflow.com/questions

问题 I have search this over on google, but no luck finding the solution. I have read this documentation but it just using pure javascript. I have read this from older post created by @Ram, but the answer didn't solve my problem, because I think maybe there's other ideas more tricky way that I don't reach it now from my current knowledge.

问题 I'm looking for a way to display math symbols and equations (coming from Latex e.g.) in Ext.js / Sencha Touch UI-Components (specifically buttons and textfields). I grasp that "ext.draw.component" might be a good starting point to develop something appropriate. Is there another way to display math? What would be your choice? Anyone came up with a solution for a similar problem already? Any advice appreciated. Best regards, Thomas 回答1: If you all you want to do is display mathematical symbols
