Props and Options

The props have to deliver changing values or objects, so bind them with v-bind: or :. In addition, value and show, encryptedValue require two-way binding, so add the .sync modifier.

class option

The class option must meet the following conditions:

• Only 'a-z' and 'A-Z', '0-9', '_', '-', ' ' can be contained
• Use ' ' to separate classes.
• The default style applies to the first class.

|property|default| |-|-| |keypadClass|'numeric-keypad'| |buttonWrapClass|'numeric-keypad__button-wrap'| |buttonClass|'numeric-keypad__button'| |deleteButtonClass|'numeric-keypad__button--delete'| |clearButtonClass|'numeric-keypad__button--clear'| |blankButtonClass|'numeric-keypad__button--blank'| |activeButtonClass|'numeric-keypad__button--active'|

styles defaults

keypadStyles :

// The font size changes automatically when the button size changes.
// fontSize = Math.min(cellWidth, cellHeight) * 0.3;
.${keypadClass} {
  position: fixed;
  z-index: ${zIndex};
  bottom: 0;
  left: 0;
  right: 0;
  height: 40vh;
  padding: 10px;
  background-color: #fff;
  border-radius: 12px 12px 0 0;
  box-shadow: 0 -4px 4px rgba(0, 0, 0, 0.15);
  color: #000;
  overflow: hidden;
  font-size: ${fontSize}px; // When fontSize != 0
}

buttonWrapStyles :

.${buttonWrapClass} {
  display: flex;
  witdth: 100%;
  height: 100%;
  justify-content: space-between;
  align-content: space-between;
  flex-wrap: wrap;
  gridGap: 5px;
}

buttonStyles :

// const width = `calc(${Math.round(1000 / columns) / 10}% - ${Math.ceil(5 * (columns - 1) / columns)}px)`;
// const height = `calc(${Math.round(1000 / rows) / 10}% - ${Math.ceil(5 * (rows - 1) / rows)}px)`;
.${buttonClass} {
  flex: 0 0 auto;
  display: flex;

.${buttonClass}.${activeButtonClass} {
  background-color: #eaeaea;
}

Tip

• Detect and act on when options are changed. (However, class-related options and encrypt are excluded)
• When options are changed, if keyRandomize is true, the key array is changed randomly.
• You can bind only one value to one keypad, or you can bind multiple values.
• You can always keep the value of the show true and adjust the position of the keypad so that the keypad can always be located in a fixed layout.
• You don't have to always bind the visible value.
• If you match the total length of the optional keyArray with the total length of the keypad, the design will not break.
• You can use Slot

<VueNumericKeypad
     :value.sync="value"
     :show.sync="show"
     :options="options"
>
 <div>Something you want</div>
</VueNumericKeypad>
