you can define the handleclick() function like this: handleClick = () => { // function code here } And then bind this to the function in the constructor of the component: constructor(props) { super(props); this.handleClick = this.handleClick.bind(this); }

The error message "uncaught typeerror: _this.handleclick is not a function at onclick" typically occurs when the handleclick() function is not properly defined or bound to the correct this context. In other words, when the button is clicked, the function is not being executed because it cannot be found or accessed. Check the scope where handleclick() is defined. Make sure it is within the same class or component where the button is rendered. If the function is defined in a different scope or component, it may not be accessible to the button. Bind this to handleclick() function. You can use the bind() method to bind this to the handleclick() function, which ensures that the function is called with the correct context.
