</ion-col>
<ion-col col-1>
<button ion-button clear icon-start icon-right (click)="delParagraph(i)"><ion-icon name="trash" color="danger"></ion-icon></button>
</ion-col>
</ion-row>
<ion-row padding>
<ion-col col-11>
<button ion-button block color="danger" id="addPharagraph" (click)="addParagraph()"><ion-icon name="add-circle"></ion-icon> add pharagraph</button>
</ion-col>
</ion-row>
</ion-grid>
<div class="tab" style="position: fixed; bottom: 0;">
<a class="tab-item" (click)="save()">Save Draft</a>
</div>
使用这些代码,我只能以一维显示数据,如下所示:
{
"title":"testing title",
"paragraph":"testing paragraph 1"
}
但我希望它以这种形式显示:
{
"title":"testing title",
"paragraph":[
{"paragraph": "testing paragraph 1"},
{"paragraph": "testing paragraph 2"},
{"paragraph": "testing paragraph 3"}
]
}
我建议如下: 类别:
data = {
"title": "testing title",
"paragraphs": [
{ "paragraph": "testing paragraph 1" },
{ "paragraph": "testing paragraph 2" },
{ "paragraph": "testing paragraph 3" }
]
}
...
addParagraph(){
this.data.paragraphs.push( { "paragraph": "" });
}
delParagraph(paragraphID){
this.data.paragraphs.splice(paragraphID,1);
}

您好,我想您应该定义段落数组而不是字符串
this.data.title = '';
this.data.paragraph = [{}] instead of '';
并将您的段落推送到this.data.paragration;)
<ion-row padding *ngFor="let paragraph of data.paragraphs; let i=index">
<ion-col col-11 class="pharagraph margin-bottom">
<ion-textarea rows="10" class="bordered" placeholder="Enter Content Paragraph" [(ngModel)]="paragraph.paragraph"></ion-textarea>
</ion-col>
<ion-col col-1>
<button ion-button clear icon-start icon-right (click)="delParagraph(i)"><ion-icon name="trash" color="danger"></ion-icon></button>
</ion-col>
</ion-row>
<ion-row padding>
<ion-col col-11>
<button ion-button block color="danger" id="addPharagraph" (click)="addParagraph()"><ion-icon name="add-circle"></ion-icon> add pharagraph</button>
</ion-col>
</ion-row>
this.data.title = '';
this.data.paragraph = [{}] instead of '';
this.data.paragraph.push({paragraph: 'My text content'});
