[英]Neo4jError: Unable to pack the given value: - Invalid input 'MERGE': expected "OPTIONS" or <EOF> error depending on the parameter passed to the cypher
[英]Value for Input Options
需要有關如何獲取輸入選項值的幫助:
<div class="input-group mb-3">
<div class="input-group-prepend">
<label class="input-group-text" for="inputGroupSelect01">Color</label>
</div>
<select class="custom-select" id="inputGroupSelect01">
<option selected>Choose...</option>
<option value="1" >Blue</option>
<option value="2">Green</option>
<option value="3">Yellow</option>
<option value="4">Orange</option>
<option value="5">Red</option>
</select>
</div>
My model is like this:
User.register({
fname: req.body.firstname,
lname: req.body.lastname,
nickname: req.body.nickname,
email: req.body.email,
color: req.body.value,
designation: req.body.designation,
username: req.body.username,
我無法獲得所選選項的價值,感謝您的幫助。 謝謝你。
要在前端和后端之間進行通信,您必須設置路由並發出 HTTP 請求。 我建議使用Axios 。
要獲得輸入值,您可以執行以下操作:
const inputValue = document.getElementById('inputGroupSelect01').value;
然后用 Axios:
async sendInputValue() {
const url = 'http://localhost:5000/'
await Axios.post(`${url}register`, inputValue)
.then(res => {
// Do whatever on success
}).catch(err => {
// Do whatever with error
}
}
然后,在您的后端:
router.post('register', (req, res) => {
// Use it however you want
}
