[英]How to get ID from a input field and DELETE by that ID in ReactJS and Axios
I want to delete a specific object with a DELETE request from Axios : 我想从Axios用DELETE请求删除特定对象:
This is my code to fill and get the object information: 这是我的代码,用于填充并获取对象信息:
const rowEvents = {
onClick: (e, row, rowIndex) => {
this.setState({
carId: this.state.cars[rowIndex].carId,
brand: this.state.cars[rowIndex].brand,
model: this.state.cars[rowIndex].model,
color: this.state.cars[rowIndex].color,
topSpeed: this.state.cars[rowIndex].topSpeed
});
}
};
When I click on the row I get the data in my input fields: 当我单击该行时,将在输入字段中获取数据:
This is my delete function 这是我的删除功能
handleDelete = carId => {
axios
.delete("https://localhost:44369/api/car/DeleteCar/", {
params: { id: carId }
})
.then(response => {
console.log(response);
});
};
To get the Id from the field I have a input hidden field like this: 为了从字段中获取ID,我有一个输入隐藏字段,如下所示:
<input type="hidden" id="carId" value={this.state.carId} />;
After the fields are filled I want to delete this object based on the ID I click on the row: 填写完字段后,我想根据ID删除该对象,然后单击该行:
<button type="submit" className="btn btn-danger mr-1" onClick={this.handleDelete(document.getElementById("carId"))}> Delete record</button>
I get the following error in my console: 我在控制台中收到以下错误:
TypeError: Converting circular structure to JSON TypeError:将圆形结构转换为JSON
I have tried to pass the parameter like this {this.state.carId}
我试图像这样传递参数{this.state.carId}
Still no succes 仍然没有成功

You don't have to pass carId
as a parameter because you are saving it to the state. 您不必将carId
作为参数传递,因为您将其保存为状态。
you can access the carId
by calling this.state.carId
您可以访问carId
通过调用this.state.carId
handleDelete = () => {
axios
.delete("https://localhost:44369/api/car/DeleteCar/", {
params: { id: this.state.carId }
})
.then(response => {
console.log(response);
});
};
Can you try doing a console.log(document.getElementById("carId"))
? 您可以尝试做console.log(document.getElementById("carId"))
吗? I suspect you are getting the whole element, not just the value that you assigned it. 我怀疑您正在获取整个元素,而不仅仅是获得您为其分配的值。 I think that changing it to onClick={this.handleDelete(document.getElementById("carId").value)}
will fix your problem. 我认为将其更改为onClick={this.handleDelete(document.getElementById("carId").value)}
可以解决您的问题。
