BusinessViewHandler.rar示例说明
在可视化查询工具栏屏蔽"保存"按钮，并在"保存"按钮之前添加"自定义保存"按钮，点击新增按钮，执行自定义操作。
修改ConfigurationPatch.js扩展点配置文件
var ConfigurationPatch = {
extensionPoints: {
BusinessView: {
handlers: [{
className: "ext.gzgs.handler.BusinessViewHandler"
}]
}
}
};
BusinessViewHandler对象实现
var util = jsloader.resolve("freequery.common.util");
var BusinessViewHandler = function(businessView) {
this.businessView = businessView;
this.queryType = this.businessView.bv.queryType;
};
lang.extend(BusinessViewHandler, "freequery.widget.Module2");
BusinessViewHandler.prototype.destroy = function() {
BusinessViewHandler.superclass.destroy.call(this);
};
BusinessViewHandler.prototype.isEnabled = function(){
return true;
}
BusinessViewHandler.prototype.readConfig = function() {
var config = {
toolbar : {
items : [ {
id : "saveEx",
image : "img/save.gif",
title : "保存",
command : "SAVE_BUSINESS",//用于下面execute方法
before : "save"
}]
}
};
return config;
};
BusinessViewHandler.prototype.execute = function(cmd, btn) {
switch (cmd) {
case "SAVE_BUSINESS":
try {
this.businessView.onSave();
}catch (e){
break;
}
break;
}
};
