I have been trying to call this function onCountRowsCompanies of prinWhole.js so that I can display the number of companies in the dashboard.js but could not. Can someone please help me out here?
printWhole.js
import React, { Component } from "react";
import axios from "axios";
import Logo from "../../common/logo";
import {Link} from "react-router-dom";
import "../style.css";
class printWhole extends Component {
constructor(props) {
super(props);
this.state = { company: [] };
this.onPrint = this.onPrint.bind(this);
this.onCountRowsCompanies = this.onCountRowsCompanies.bind(this);
}
componentDidMount() {
axios
.get("http://localhost:4000/api/company")
.then(response => {
this.setState({ company: response.data });
})
.catch(function(error) {
console.log(error);
});
}
componentDidUpdate() {
axios
.get("http://localhost:4000/api/company")
.then(response => {
this.setState({ company: response.data });
})
.catch(function(error) {
console.log(error);
});
}
onPrint = e => {
e.preventDefault();
document.getElementById("hide").style.visibility="hidden";
window.print();
document.getElementById("hide").style.visibility="visible";
};
/**This is the function onCountRowsCompanies that I want to call in Dashboard.js to display the number of companies**/
onCountRowsCompanies = e => {
e.preventDefault();
var totalRowCount = 0;
var rowCount = 0;
var table = document.getElementById("css-serial");
var rows = document.getElementsByTagName("tr");
for( var i = 0; i < rows.length; i++){
totalRowCount++;
if(rows[i].getElementsByTagName("td").length > 0){
rowCount++;
}
}
let message = "Total number of companies so far " + rowCount;
//alert(message);
document.getElementById("displayMessage").innerHTML = message;
};
render() {
const company = this.state.company;
return (
<div className="mt-5 mb-5">
