OnClick Function does not work on Chrome? - javascript

I am trying to use onClick function on react.js HTML select option and it works perfectly on Firefox but not on Chrome. How can I make it work in Chrome? Here is my code so far:
import React, { Component } from "react";
import DateRangePicker from "react-daterange-picker";
import "react-daterange-picker/dist/css/react-calendar.css";
import originalMoment from "moment";
export class Filter extends Component {
constructor(props, context) {
super(props, context);
this.state = {
isOpen: false,};
}
onToggle = () => {
this.setState({ isOpen: !this.state.isOpen });
};
render() {
return (
<div className="filter_range">
<select
class="form-control donn"
name="today"
>
<option selected disabled hidden>
Choose{" "}
</option>
<option value="today">Today</option>
<option value="yesturday">Yesterday</option>
<option>Last Week</option>
<option value="month">Last Month</option>
<option>Last Quarter</option>
<option value="year">Last Year</option>
<option value="">Overall</option>
<option value="" onClick={this.onToggle}>
Custom
</option>
</select>
{this.state.isOpen && (
<DateRangePicker
value={this.props.value}
onSelect={this.props.change}
singleDateRange={true}
isOpen={false}
maximumDate={new Date()}
closeCalendar={true}
numberOfCalendars={2}
showLegend={true}
locale={originalMoment().locale()}
/>
)}
</div>
);
}
}
export default Filter;

Try to use onChange instead of onClick for select element.
<select class="form-control donn" name="today" onChange={handleChange}>
Just add value to your custom option and check for it in the if statement
<option value="custom">
Custom
</option>
export class Filter extends Component {
constructor(props, context) {
super(props, context);
this.state = {
isOpen: false,
};
}
handleChange = (event) => {
if (event.target.value === "custom") {
this.setState({ isOpen: !this.state.isOpen });
}
};
render() {
return (
<div className="filter_range">
<select class="form-control donn" name="today" onChange={handleChange}>
<option selected disabled hidden>
Choose{" "}
</option>
<option value="today">Today</option>
<option value="yesturday">Yesterday</option>
<option>Last Week</option>
<option value="month">Last Month</option>
<option>Last Quarter</option>
<option value="year">Last Year</option>
<option value="">Overall</option>
<option value="custom">
Custom
</option>
</select>
{this.state.isOpen && (
<DateRangePicker
value={this.props.value}
onSelect={this.props.change}
singleDateRange={true}
isOpen={false}
maximumDate={new Date()}
closeCalendar={true}
numberOfCalendars={2}
showLegend={true}
locale={originalMoment().locale()}
/>
)}
</div>
);
}
}
export default Filter;

Option onClick - Unnecessary
You can put onChange in the select tag
The select onChange trigerd when option is clicked (changed).

You can have a child component that only renders the option tag. You actually don't need to add an event handler to the option tag. The select onChange event get called automatically once an option tag is clicked (passing it's value with it).

Next js form data doesn't change according to the URL queries

My question is that I am doing data filtering using formik and I change the query of the URL when I submit the form and it worked. now the problem is that when I open a new tab in the browser and paste the URL with the queries in it the form value "the select element value" does not change according to the URL queries. I tried to debug it but I failed.
import Head from "next/head";
import { Formik, Field, Form } from "formik";
import router, { useRouter } from "next/router";
import { useState, useEffect } from "react";
export default function Home() {
const { query } = useRouter();
const [initialValues, setInitialValues] = useState({
categories: query.categories || "all-categories",
color: query.color || "all-color",
size: query.size || "all-size",
});
return (
<div>
<Head>
<title>Create Next App</title>
<meta name="description" content="Generated by create next app" />
</Head>
<Formik
initialValues={initialValues}
onSubmit={(values) => {
router.push({ pathname: "/", query: values }, undefined, {
shallow: true,
});
}}
>
<Form>
<Field label="categories" as="select" name="categories">
<option value="all-categories">get all</option>
<option value="electronics">electronics</option>
<option value="jewelery">jewelery</option>
<option value="men-clothing">men's clothing</option>
<option value="women-clothing">women's clothing</option>
</Field>
<Field label="categories" as="select" name="color">
<option value="all color">all color</option>
<option value="red">Red</option>
<option value="black">Black</option>
<option value="white">White</option>
</Field>
<Field label="size" as="select" name="size">
<option value="all-size">all size</option>
<option value="s">S</option>
<option value="m">M</option>
<option value="l">L</option>
<option value="xl">XL</option>

<button type="submit">Submit</button>

onClick event not working with option tag in React

onClick event not working with <option> tag. How to use onClick event with select option tag. Each option must be given a different parameter.
async function localization(language) {
localStorage.setItem("language", language);
}
useEffect(() => {
localization(localStorage.getItem("language"));
}, []);
return(
<select>
<option onClick={() => localization("ru")}>
<RussinFlagIcon /> Ru
</option>
<option onClick={() => localization("uz")}>
<UzbekistanFlagIcon /> Uz
</option>
<option onClick={() => localization("en")}>
<UKFlagIcon /> En
</option>
</select>
)
Use onChange instead, it's how you should be working when it comes to <select>. You can do something like this:
Notice value attribute on <option>. The selected option's value will be the value of the <select>.
return(
<select onChange = {(e)=> localization(e.target.value)}>
<option value = "ru">
<RussinFlagIcon /> Ru
</option>
<option value= "uz">
<UzbekistanFlagIcon /> Uz
</option>
<option value="en">
<UKFlagIcon /> En
</option>
</select>
)
Normally the select is used with a [form][1], then you should use the onChange callback:
const Select = () => {
const handleChange = (e) => localStorage.setItem("language", e.target.value);
return (
<label>
<select name="languages" onChange={handleChange}>
<option onClick={() => localization("ru")}>
<RussinFlagIcon /> Ru
</option>
<option onClick={() => localization("uz")}>
<UzbekistanFlagIcon /> Uz
</option>
<option onClick={() => localization("en")}>
<UKFlagIcon /> En
</option>
</select>
</label>
);
};
Then some comments about your code:
Your async function localization does not have to be async if you don't have a Promise in it.
And your useEffect does not do much except store the language in the localStorage based on the localStorage value ...

Using Array.map in react.js

I tried to use option from database using native select of material UI,but error is shown.what may be the issue ?what may be the solution for the problem?How can i solve the issue?
Please provide me a solution.
Looking at the constructor within the component, the salaryDetails state is initialised as an empty string, ''.
Array.map() can only be used on arrays. THerefore, you should be initialising your salaryDetails state as an empty array.
this.state = {
salaryDetails: [],
data: {
employeeName: '',
year: '',
month: '',
},
}

React - How to get input from looped <form>?

I am new on React.
I have a condition which is to loop the form, please help me
Here is the code:
this.state.products.map(product => {
<form onSubmit={this.handleSubmit}>
<select name="size" className="form-control" style={{height: '46px;'}}>
<option key="1" value="1">Red</option>
<option key="2" value="2">Yellow</option>
<option key="3" value="3">Green</option>
</select>
<input type="submit" value="Pick This" className="form-control" onClick={() => this.handleSubmit} />
</form>
});
If there was 3 form, how to get the selected value from clicked submit button form?
Or is there another simple way?
Thank you
One method would be changing how your onSubmit function is handled.
So you could pass which index of products you are submitting like so
this.state.products.map((product, i) => {
<form onSubmit={event => this.handleSubmit(event, i)}>
<select name="size" className="form-control" style={{height: '46px;'}}>
<option key="1" value="1">Red</option>
<option key="2" value="2">Yellow</option>
<option key="3" value="3">Green</option>
</select>
<input type="submit" value="Pick This" className="form-control" onClick={() => this.handleSubmit} />
</form>
});
It also looks like your form is uncontrolled, which another possibly is having the select change a value in state.
<select name="size" onChange={e => this.handleChange(e, i)} className="form-control" style={{height: '46px;'}}>
<option key="1" value="1">Red</option>
<option key="2" value="2">Yellow</option>
<option key="3" value="3">Green</option>
</select>
and in your handleChange, you would change a value in state that would correspond to the product from your state.
You can use a ref to get form values from the DOM.
Here you need one ref per product, so you could use the index of product to save the ref and also to submit de form.
class Example extends Component {
constructor(props) {
super(props);
this.state = {
products: [],
};
this.selectByProduct = {};
this.handleSubmit = this.handleSubmit.bind(this);
}
handleSubmit(event, productIndex) {
event.preventDefault();
const size = this.selectByProduct[productIndex].value;
console.log(`you submitted the size ${size} of product ${productIndex}`)
}
render() {
return this.state.products.map((product, i) => (
<form onSubmit={event => this.handleSubmit(event, i)}>
<select ref={select => this.selectByProduct[i] = select} name="size" className="form-control" style={{height: '46px;'}}>
<option key="1" value="1">Red</option>
<option key="2" value="2">Yellow</option>
<option key="3" value="3">Green</option>
</select>
<input type="submit" value="Pick This" className="form-control" />
</form>
));
}
}

addResults options doesn't work in bootstrap-select

I would like to use addResults option in bootstrap-select to add new items. I should be prompted to add search string, but I get default message No Results.
jsfiddle
component.jsx
class TodoApp extends React.Component {
constructor(props) {
super(props);
}
componentDidMount() {
$(this.selectPicker).selectpicker({
liveSearch: true,
addResults: true,
});
}
render() {
return (
<div>
<select className="form-control" data-width="100%" ref={el => (this.selectPicker = el)}>
<optgroup label="Group 1">
<option defaultValue>Team</option>
<option value="1">AAA</option>
</optgroup>
<optgroup label="Group 2">
<option value="2">BAC</option>
<option value="3">BAY</option>
</optgroup>
