Ionic 2无法查看离子项目内部的跨度,如何呈现简单文本 [英] Ionic 2 Cannot view span inside of ion-item, how to render simple text
问题描述
我不确定是否丢失了某些东西,但是当我尝试向离子项目添加跨度时,该跨度不会呈现,也不会显示div.
I'm not sure if I'm missing something, but when I try to add a span to a Ion Item the span is not rendered, nor div.
<ion-card>
<ion-card-title>
</ion-card-title>
<div>
<button ion-button (click)="toggleEdit()">Edit</button>
</div>
<ion-list>
<ion-card-content>
<ion-item [hidden]="editOptions.!isEditing">
<span class="inline-edit">Text</span>
<ion-label color="primary">{{label}}</ion-label>
<ion-input></ion-input>
<span class="inline-edit">{{value}} </span>
</ion-item>
<ion-item [hidden]="!editOptions.isEditing">
<ion-label color="primary">{{label}}</ion-label>
<ion-input [(ngModel)]="value" [required]="required" [type]="type" [name]="value"></ion-input>
</ion-item>
</ion-card-content>
</ion-list>
</ion-card>
离子标签和输入可以正常显示,但当我尝试在Item中使用跨度或div时,它们不会呈现.即使当我用铬检查它们时.
Ion label and Input display and work fine, but how when I try to use a span or a div in an Item they aren't rendering. Even when I inspect them in chrome.
如何呈现简单的文本,我不允许在组件中使用HTML吗? Ionic 2可以用来渲染少量文本的方法是什么,看来标签必须始终位于输入上方,那么我应该使用哪个组件?
How can I render simple text, Am I not allowed to use HTML in a component? What Is the Ionic 2 equivently for rendering small amounts of text, it appears labels have to always be over an input, so what component should I use?
推荐答案
这是因为内容投影的工作原理,ion-item
仅会渲染某些组件(例如ion-label
和ion-input
),但会忽略某些组件其他html元素.
That's because of how content projection works, the ion-item
will only render some components (like the ion-label
and the ion-input
) but will ignore some other html elements.
也许还有其他方法可以修复它,但是AFAIK有两种选择:
There may be other ways to fix it, but AFAIK you have two choices:
1)如果文本只是小文本,则可以使用注释一个>.
1) If the text is just a small text , you can use notes.
注释是离子项目中的详细项目.它创建了灰色元素 可以在项目的左侧或右侧.
A note is detailed item in an ion-item. It creates greyed out element that can be on the left or right side of an item.
<ion-content>
<ion-list>
<ion-item>
<ion-note item-start>
Left Note
</ion-note>
My Item
<ion-note item-end>
Right Note
</ion-note>
</ion-item>
</ion-list>
</ion-content>
然后您可以使用样式规则以使其适应您的方案.
You can then play with the style rules to adapt it to your scenario.
2)将item-start
,item-end
,item-left
,item-right
或item-content
属性添加到忽略的html元素.
2) Add the item-start
, item-end
, item-left
, item-right
or item-content
attribute to the ignored html elements.
Attribute Description
item-start Placed to the left of all other elements, outside of the inner item.
item-end Placed to the right of all other elements, inside of the inner item, outside of the input wrapper.
item-content Placed to the right of any ion-label, inside of the input wrapper.
请查看此导航键,以便您可以使用这些属性,直到您获得所需的布局.
Please take a look at this plunker so you can play with those attributes until you get the desired layout.
<ion-item style="background: transparent;">
<span item-content class="inline-edit">Text</span>
<ion-label color="primary">Label</ion-label>
<ion-input></ion-input>
<span item-content class="inline-edit">Value</span>
</ion-item>
