[value]和Angular中的value有什么区别，检查null值的方法是什么？

Question

<mat-form-field>
    <input matInput placeholder="Organization name" [value]="organizationDetail.name"
        formControlName="organizationName" required>
</mat-form-field>

检查organizationDetail.name是否为空的方法是什么？我遇到错误

错误TypeError：无法读取null的属性'名称'

在我的.ts文件中，我将其初始化如下：

organizationDetail: any = {};

constructor() {
    this.organizationDetail = {
        address: '',
        attachmentId: null,
        createdBy: '',
        createdDateTime: '',
        industryFramework: [],
        invitation: [],
        location: '',
        name: '',
        orgAssessment: [],
        organizationId: 0,
        organizationPolicy: [],
        ownerId: 0,
        partnerType: null,
        partnerTypeId: 0,
        phone: '',
        updateBy: '',
        updateDateTime: '',
        user: [],
    };
}

感谢您的帮助。我找不到任何可以帮助我识别出差异并解决错误的好文章。
