通过循环添加段落文本输入[TypeScript]

Question

我在TypeScript中有这个变量：

data = {
    "paragraphs": [
        { "paragraph": "" }
    ]
}

加载屏幕后，我想在数组中添加{ "paragraph": "" }，如下所示。

data = {
    "paragraphs": [
        { "paragraph": "" },
        { "paragraph": "" },
        { "paragraph": "" }
    ]
}

所以我做的是，我做了一个for循环来继续在数组中添加{ "paragraph": "" }但是它还没有完成。

let dataParag = 3;      // The int value will keep changing based on data from database
for (var i = this.data.paragraphs.length; i <= dataParag; i++) {
    this.data.paragraphs = [
        { "paragraph": "" }     // The paragraph will be keep added in here but I don't have any idea on how to add it
    ];
}

有没有什么好方法可以动态添加它？

哦，我从未找到解决方案。这就是我做的事情：

let dataParag = 3;
for (var i = 1; i < dataParag; i++) {
    this.data.paragraphs.push({ "paragraph": "" });
}
