Extjs 4网格悬停效果 [英] Extjs 4 Grid hover effect

问题描述

我正在使用extjs 4 n导轨。我有网格，有列作为超链接的文件名。我想在文件名的悬停效果上显示图像。图像在数据库中保存为二进制。现在我想在网格中显示文件名悬停效果的图像。

I am working with extjs 4 n rails. i have grid that has column as filename which is hyperlink. i want to display image on hover effect of filename. the image is saved as binary in database. now i want to display image on hover effect of filename in grid.

推荐答案

我会在视图中放置一个侦听器，然后将其显示为普通< img src ='your url'>在工具提示或其他容器中

i would put a listener on mouseover in the view and then show it as an ordinary <img src='your url'> in a tooltip or other container

viewConfig: {stripeRows: false, trackOver:true},
selType: 'cellmodel',
columns: [
  {text: "Filename", dataIndex: 'filename', 
    listeners: {
      'mouseover': function(){
        //show your container
      }
    }
  },
