The maximum value of the slider corresponds to the total number of elements in the array

As I work on constructing a Material UI Slider, I have a specific requirement. I want the maximum value of my slider to dynamically adjust according to the number of items in an array of options.

['Answer1', 'Answer2', 'Answer3', 'Answer4'];

For instance, if there are 4 options as shown above, but in different scenarios, there might be 3 or 5 options. Therefore, when setting up my Slider component:

<Slider
 classes={{ container: classes.slider }}
 value={value}
 min={1}
 max={4}
 onChange={this.handleChange}
/>

Instead of hard-coding the max value as 4, it should be determined by the length of my array (not limited to 4). Perhaps using something like myArray.length? How can I integrate this dynamic functionality into my React component?

Answer №1

To display the total number of items in your array, simply access the .length property of your array:

<Slider
 classes={{ container: classes.slider }}
 value={value}
 min={1}
 max={yourArray.length}
 onChange={this.handleChange}
/>
