Xpages将值添加到组合框中 [英] Xpages add values into Combo Box

问题描述

我有一个组合框，我想有可能使用按钮和输入字段在组合框中添加新的值。我试过：

  var value = getComponent（input）。getValue 
 getComponent（combobox）。setValue（value）; 
  

但不起作用。

解决方案

使用viewScope例如 viewScope.selectItems 变量。

• 将此viewScope用作selectItems列表。


• 向其添加初始值。


• 稍后，向此viewScope添加一个新项，然后它将出现在combobox的选择项列表中。

这是一个工作示例：

 < xp：comboBox 
 id =comboBox1
 value =＃{sessionScope.test}> 
< xp：selectItems> 
< xp：this.value><！[CDATA [＃{javascript：
 if（！viewScope.selectItems）{
 viewScope.selectItems = [your，initial ，values]; 
} 
 return viewScope.selectItems;}]]>< / xp：this.value> 
< / xp：selectItems> 
< / xp：comboBox> 
< xp：inputText 
 id =inputText1
 value =＃{viewScope.newItem}> 
< / xp：inputText> 
< xp：button 
 value =添加到selectItems
 id =button1> 
< xp：eventHandler 
 event =onclick
 submit =true
 refreshMode =complete> 
< xp：this.action><！[CDATA [＃{javascript：
 viewScope.selectItems.add（viewScope.newItem）; 
 viewScope.newItem =; 
}]]>< / xp：this.action> 
< / xp：eventHandler> 
< / xp：button> 
  

I have a Combo Box and I would like to have the possibility to add new values in the Combo Box using a button and an Input Field. I tried with:

var value = getComponent("input").getValue(); 
getComponent("combobox").setValue(value);

but it is not working.

Thank you,

解决方案

Use a viewScope e.g. viewScope.selectItems variable.

• Use this viewScope as the selectItems list.
• Add the initial values to it.
• Later, add a additional new item to this viewScope and then it will appear in combobox's selection item list.

This is a working example:

<xp:comboBox
    id="comboBox1"
    value="#{sessionScope.test}">
    <xp:selectItems>
        <xp:this.value><![CDATA[#{javascript:
        if (!viewScope.selectItems) {
            viewScope.selectItems = ["your","initial","values"];
        }
        return viewScope.selectItems;}]]></xp:this.value>
    </xp:selectItems>
</xp:comboBox>
<xp:inputText
    id="inputText1"
    value="#{viewScope.newItem}">
</xp:inputText>
<xp:button
    value="Add to selectItems"
    id="button1">
    <xp:eventHandler
        event="onclick"
        submit="true"
        refreshMode="complete">
        <xp:this.action><![CDATA[#{javascript:
            viewScope.selectItems.add(viewScope.newItem); 
            viewScope.newItem = "";
        }]]></xp:this.action>
    </xp:eventHandler>
</xp:button>
