I have two dropdowns pretty similar, both have an 'onChange' event:

    <Dropdown
      items={employeeNames}
      selection={employeeNames.name}
      onChange={this.handleEmployeeNamesChange}
    />
    <Dropdown
      items={employeeTypes}
      selection={employeeType.name}
      onChange={this.handleEmployeeTypeChange}
    />

Is there a way I can combine the two handleChange function to one function:

  handleEmployeeNameChange = newVal => {
    const newState = { ...this.state, employeeNames: newVal };
    this.setState({ ...newState, isValid: getValidation(newState) });
  };

  handleEmployeeTypeChange= newVal => {
    const newState = { ...this.state, employeeTypes: newVal };
    this.setState({ ...newState, isValid: getValidation(newState) });
  };

You could create a factory method that creates functions for each change handler you want

handleGenericChange = changedProperty => newVal => {
    const newState = { ...this.state, [changedProperty]: newVal };
    this.setState({ ...newState, isValid: getValidation(newState) });
}

handleEmployeeNameChange = handleGenericChange('employeeNames')
handleEmployeeTypeChange = handleGenericChange('employeeTypes')

Handling Multiple Inputs with a Single onChange Handler in React , With a text input field like this, we can pass the onChange prop: The value of the prop is the handleChange function; It is an event handler. To do this, we'll add some React state and set the input field's value prop with it: many other types of input fields so that they are consumed in a very similar way. javascript The value of the prop is the handleChange function; It is an event handler. The event that the handler receives as a parameter is an object that contains a target field. This target is the DOM element that the event handler is bound to (ie, the text input field).

It's up to you to create a method to combine your changes and pass parameters.

The final goal is to update the right key of your state, use this key as parameter.

<Dropdown
  items={employeeNames}
  selection={employeeNames.name}
  onChange={v => this.handleChangeDropdown("employeeNames",v)}
/>
<Dropdown
  items={employeeTypes}
  selection={employeeType.name}
  onChange={v => this.handleChangeDropdown("employeeTypes",v)}
/>

handleChangeDropdown = (key,newVal) => {
  this.setState({
     [key]:newVal,
     isValid: getValidation(newState)
  })
};

Add two functions to 'onchange'?, The options are dependable on each other, meaning that whenever an Join Date: Dec 2009; Posts: 48; Thanks: 2: Thanked 0 Times in 0 Posts Can I, and if I canhow can I tell the onchange function to do two things: But, yes, two functions are easy, using the same syntax as in regular Javascript: Use the Uniform Event Model and document.getElementByWhatever("").addEventListener(). Otherwise, just call multiple functions together. Otherwise, just call multiple functions together. For example

Use arrow function on change and add name of state you want to change

<Dropdown
  items={employeeNames}
  selection={employeeNames.name}
  onChange={(v) => this.handleEmployeeChange('employeeNames', v)}
/>
<Dropdown
  items={employeeTypes}
  selection={employeeType.name}
  onChange={(v) => this.handleEmployeeChange('employeeTypes', v)}
/>

And

  handleEmployeeChange = (field, newVal) => {
    const newState = { ...this.state, field: newVal };
    this.setState({ ...newState, isValid: getValidation(newState) });
  };

Functions and Change: A Modeling Approach to College Algebra, Thus a formula for this part of the roof line is R : —0.25h + 18, with h and R as In the next example, we will need to weave together two formulas to make a single piecewise-defined function. despite the different formulas that could give different values for the same year. 5.4 Combining and Decomposing Functions 459. Tip: This event is similar to the oninput event. The difference is that the oninput event occurs immediately after the value of an element has changed, while onchange occurs when the element loses focus, after the content has been changed. The other difference is that the onchange event also works on <select> elements.

Sounds like a code review question. Yes, there is :

handleEmployeeChange = category => newVal => {
   const newState = { ...this.state, [category]: newVal };
   this.setState({ ...newState, isValid: getValidation(newState) });
};

Setting a second argument to your arrow function allow it to be preconfigured for later use :

<Dropdown
  items={employeeNames}
  selection={employeeNames.name}
  onChange={this.handleEmployeeChange('employeeNames')}
/>
<Dropdown
  items={employeeTypes}
  selection={employeeType.name}
  onChange={this.handleEmployeeChange('employeeTypes')}
/>

You can even map your Dropdown components to avoid any repetition :

['employeeNames', 'employeeTypes'].map(param => {
    <Dropdown
        items={data[param]}
        selection={data[param].name}
        onChange={this.handleEmployeeChange(param)}
        key={data[param].name} //If their name is unique
    />
})

Your values will just have to be in an object :

data = {
    employeeNames: '',
    employeeTypes: ''
}

The Aggregate Production Function and the Measurement of Technical , If we follow this advice, then, of course, the concept of the production function at The technical literature on this is quite complicated and we review it briefly in the Does it make any sense to combine the values of each of the outputs and the two industries and estimate a production function that purportedly represents  I have a textbox in which am calling 2 js functions a and b() on onchange event of that textbox. Function b should be executed only if a returns true.I have tried the following code but function b

you can do like this:

    <Dropdown
      items={employeeNames}
      selection={employeeNames.name}
      onChange={this.handleEmployeeChange.bind(this, "name")}
    />

   <Dropdown
      items={employeeTypes}
      selection={employeeType.name}
      onChange={this.handleEmployeeChange.bind(this, "type")}
   />

in declaration

handleEmployeeChange(val){
    val === "name" ? const newState = { ...this.state, employeeNames: newVal };
    this.setState({ ...newState, isValid: getValidation(newState) });
    : 
    const newState = { ...this.state, employeeTypes: newVal };
    this.setState({ ...newState, isValid: getValidation(newState) });
}

Annals of Mathematics, does not change the angle between any two intersecting curves, and a circle the two spheres for all functions of the same type is known, and by projecting The transformation s, = ~ rotates the sphere 180° about the diameter joining + 1, — 1. other by substituting - for z ; therefore if we have the figure for either function  The two Worksheet_Change events are quite the same, they are a loop around a range, returning LCase().Thus, it is a good idea to make a separate Sub for it like this: Sub FixRangeLCase(rangeToFix As Range) Dim myCell As Range For Each myCell In rangeToFix myCell.Value2 = LCase(myCell.Value2) Next myCell End Sub

Colin, if you're still around, why did you use "change" in there instead of "onchange"? I completed the challenge, but it doesn't explain where "change" came from. If it were .click, we would add "click" in the event listener, so why is this different? And what is "change"? How is "change" different from "onchange"?

  • declare one function and when you are calling it on onClick pass a argument let say "name" and type for another one and check it where you have declared and set the state as you wanted
  • Ahah same answer at the same time, I keep mine who's write with a different syntax
