传递extJs网格值来存储PHP脚本

I currently have a simple extJS Grid which is pulling data from a server and presenting it to the viewer. I would like to grab the value of the selected row, and then pass it to another PHP script for processing in order to display the results in another grid.

我现在有一个简单的extJS网格，它从服务器中提取数据并将其呈现给查看器。我想获取所选行的值，然后将其传递给另一个PHP脚本进行处理，以便在另一个网格中显示结果。

var roleInformationStore = Ext.create('Ext.data.Store', {
  autoLoad: true,
  autoSync: true,
  model: 'RoleInformation',
  proxy: {
    type: 'ajax',
    url: 'data.php',
    reader: {
      type: 'array',
    },
    writer: {
      type: 'json'
 }
}
});

var roleInformationGrid = Ext.create('Ext.grid.Panel', {
  store: roleInformationStore,
  width: '100%',
  height: 200,
  title: 'Roles',
  columns: [
  {
    text: 'Name',
    flex: 1,
    width: 100,
    sortable: false,
    hideable: false,
    dataIndex: 'role'
 }
 ],
 listeners: {
   cellclick: function(view, td, cellIndex, record, tr, rowIndex, e, eOpts) {
     roleInformationStore.proxy.extraParams = record.get('role');
    //Ext.Msg.alert('Selected Record', 'Name: ' + record.get('role'));
   }
 }
});

Using the listener in the current grid, I am able to get the value and show it using the alert method. Any suggestions on how to accomplish this?

使用当前网格中的侦听器，我可以获取值并使用alert方法显示它。有什么建议吗?

Thanks

For this to work, extraParams has to be an object of key-value string pairs, because an URI has to be something like data.php?key1=value1&key2=value2.

要实现这一点，extraParams必须是键值字符串对的对象，因为URI必须是类似data.php?key1=value1&key2=value2的东西。

Style-wise, Sencha advises to use getters and setters, whenever possible.

在风格上，Sencha建议尽可能使用getter和setter方法。

Together, you get:

在一起,你会:

var store = Ext.getStore("roleInformationStore");
store.getProxy().setExtraParam("myRoleParamKey",record.get('role'));
store.load();

In PHP, you would get the parameter then using

在PHP中，您将获得参数然后使用。

$role = $_GET['myRoleParamKey'];

You can of course substitute myRoleParamKey for any alphanumeric literal you want, but make sure you use the same key on both server and client side. ;-)

当然，可以将myRoleParamKey替换任何你想要的字母数字文字，但是要确保在服务器和客户端都使用相同的键。:-)
