问题描述
我正在尝试调用格式化程序.例如将文本转换为大写.我有两个格式化程序,一个在控制器中,一个在 utils 文件夹中.
I am trying to call a the formatter. e.g. to transform a text to uppercase. I have two formatters, one is in the controller and one is globally in the utils folder.
我试图调用两者,但没有调用.有人可以帮我吗:(?
i tried to call both, but none is called. Can someone help me please :(?
我在 utils 文件夹中有一个全局格式化程序:
I have a global formatter in utils folder:
jQuery.sap.declare("my.app.util.Formatter");
my.app.util.Formatter = {
toUpperCase: function(sStr) {
return sStr.toUpperCase();
}
};
和我的控制器中的一个格式化程序(我也执行 require $.sap.require("my.app.util.Formatter");
):
and one formatter in my controller (i do the require $.sap.require("my.app.util.Formatter");
as well):
myControllerToUpperCaseFormatter : function(sStr) {
console.log('I WILL DO NOTHING!');
return sStr.toUpperCase();
}
我的 XML:
<mvc:View controllerName="my.app.view.XXX"
xmlns:core="sap.ui.core" xmlns:mvc="sap.ui.core.mvc" xmlns:l="sap.ui.layout"
xmlns:f="sap.ui.layout.form" xmlns:c="sap.ui.core" xmlns="sap.m">
<Page class="sapUiFioriObjectPage" title="Test">
<content>
<Button text="{path: 'MyModel>/name', formatter: 'my.app.util.Formatter.toUpperCase'}"></Button>
<Button text="{path: 'MyModel>/name', formatter: '.myControllerToUpperCaseFormatter' }"></Button>
</content>
</Page>
感谢您的帮助!
推荐答案
您的绑定看起来不正确
MyModel>/name
//它声明 name 是数据属性层次结构根部的一个属性.正确的方法:
MyModel>/name
// it states that name is a property at the root of the data property hierarchy.Right Way:
<Button text="{path: 'MyModel>name', formatter: '.myControllerToUpperCaseFormatter' }"></Button>
尽管如此,我有时也遇到过这个问题!
Nevertheless, I too sometimes have faced this issue!
出于某种原因,当使用两个或更多参数时,它开始工作.
For some reason, when two or more parameters are used it started working.
示例:
<Button text="{parts:[{path:'MyModel>name'},{path:'MyModel>somethingElse'}],formatter: '.myControllerToUpperCaseFormatter' }"></Button>
其他解决方案:
看起来您正在绑定来自 UI 控制器的数据.如果是,请格式化您想要的数据,然后将其设置为模型.
Looks like you are binding the data from UI controller.If yes, format the data you want and then set it to model.
