我遇到了钛合金的问题。我似乎无法访问从控制器在XML中声明的3d级嵌套对象。
这是XML中的布局:
<Alloy>
<Collection src="reportDetails"/>
<Window class="container" title="Update Report Details" onClose="cleanup" >
<View id="labels">
<TextArea id="jobTitle" class="title bold" editable="false"></TextArea>
<View class="jobTitleSecondPart" >
<Label class='bold'>last date od service: </Label>
<Label id="jobDate" class="stickLeft"></Label>
<Label class='bold'>Job ID: #</Label>
<Label id="jobId" class="stickLeft"></Label>
</View>
</View>
<ActivityIndicator id="busy"></ActivityIndicator>
<View height="Titanium.UI.FILL">
<ScrollView id="scrollIns" layout="vertical" dataCollection="reportDetails" dataFilter="filterFunction" height="Titanium.UI.FILL">
<View id="instruction"> <!-- ***I am trying to access this object in the controlle***r -->
<Label class="title bold black">Agent Instructions :</Label>
<Label platform="android" id="jobInstruction" html="{agentInstructions}" class="black" height="Titanium.UI.SIZE" />
<WebView platform="ios" id="jobInstruction" html="{agentInstructions}" class="black" touchEnabled="false" height="Titanium.UI.SIZE" />
</View>
<View id="comment">
<Label class="title bold black">Agent Comment :</Label>
<Label id="jobComment" class="black" text="{reportComment}"></Label>
</View>
<Require src="reportImageGallery" images="{images}"/>
</ScrollView>
<View id="buttons">
<Button id="btnInsert" class="bold" onClick="showInsertReport">Insert Update Reports</Button>
</View>
</View>
</Window>
</Alloy>
这是来自控制器的代码行:
$。instruction.visible = false;
这就是它给我的错误:
message =“undefined不是对象(评估'$ .instruction.visible = false')”;
答案 0 :(得分:1)
@Turtle是正确的,数据绑定的父元素(使用dataCollection
)内的ID不能用于通过$.<id>
到达它们,因为会有多个实例。
