The Code is as follows:

Ext. Ajax. request ({
Method: 'post', // Request method
Params: {dagl_code: dagl_code },
Url: lcwPath + "/daxt/lcgl.shtml? Method = getJgBycode ", // request url
Success: function (response, opts ){
If (response. responseText! = '{}'){
Alert (response. responseText );
// Method 1
Var dagl_jg = Ext. util. JSON. decode (response. responseText). dagl_jg;
// Method 2
Var json = eval ("(" + re. responseText + ")");
Var dagl_jg = json. dagl_jg;

Var org_mc = Ext. util. JSON. decode (response. responseText). org_mc;
Var lccode = Ext. util. JSON. decode (response. responseText). lccode;
Var lcname = Ext. util. JSON. decode (response. responseText). lcname;
Ext. getCmp ("jgs"). comboHidden. setValue (dagl_jg );
Ext. getCmp ('jgs '). setValue (org_mc );
Ext. getCmp ('dagl _ jg'). setValue (dagl_jg );
Ext. getCmp ('sslc '). setValue (lccode );
Ext. getCmp ('sslc '). setRawValue (lcname );

Var dagl_jg = Ext. getCmp ('jggs'). comboHidden. getValue ();
LcStore. proxy = new Ext. data. HttpProxy ({url: lcwPath + '/daxt/lcgl.shtml? Method = getDaxx & dagl_type = L & dagl_jg = '+ dagl_jg });
LcStore. load ();
Ext. getCmp ('lcbh'). setValue ('');
} Else {// no value. Clear the information.
