积极修改塔佩斯里的表格背景信息 5
原标题:Modifying FormInjector context information in Tapestry 5 dynamically
最佳回答

利用环境参数通过动态价值,这并不是我的第一个选择。 (FormInjector 构成部分生成了URL,以启动活动手稿,然后包括背景,但当构成部分提供,而且无意成为动态时,就这样做了。)

我删除了环境参数,找到了不同的提交价值的方法。 一种可能性是,通过美国宇宙航空研究开发机构提交表格,并在回击中引发注射:

this.myFormElement.observe( change , this.onChange.bindAsEventListener(this));

...

onChange: function(event) {
    this.myFormElement.form.request({
           onSuccess: this.afterFormSubmitted.bind(this)
    });
},

afterFormSubmitted: function() {
   this.formInjector.trigger();
}

这样,当你触发注射形式时,形式要素的价值就在服务器方面确定,你可以在注射活动中使用。
