throttle(delay, noTrailingopt, callback, debounceModeopt) → {function}

Throttle execution of a function. Especially useful for rate limiting execution of handlers on events like resize and scroll.

Example
throttle(300, () => {  });
 debounce(300, () => {  });
 // cancel
 const throttled = throttle(300, () => {  });
 throttled.cancel();
Parameters:
Name Type Attributes Description
delay Number

A zero-or-greater delay in milliseconds. For event callbacks, values around 100 or 250 (or even higher) are most useful.
noTrailing Boolean <optional>

Optional, defaults to false. If noTrailing is true, callback will only execute every delay milliseconds while the throttled-function is being called. If noTrailing is false or unspecified, callback will be executed one final time after the last throttled-function call. (After the throttled-function has not been called for delay milliseconds, the internal counter is reset)
callback function

A function to be executed after delay milliseconds. The this context and all arguments are passed through, as-is, to callback when the throttled-function is executed.
debounceMode Boolean <optional>

If debounceMode is true (at begin), schedule clear to execute after delay ms. If debounceMode is false (at end), schedule callback to execute after delay ms.
Returns:

A new, throttled, function.

Type
function

toHexAlphaColor(hex, alpha) → {String}

将 hex color 添加上 alpha

Example
toHexAlphaColor('#efefef', 0.56); // #efefef8F
Parameters:
Name Type Description

 toHexColor('rgba(241,112,19, 1)'); // #f17013
 toHexColor('rgba(241,112,19, 0.1)'); // #f17013
 toHexColor('red'); // #ff0000
 toHexColor(); // ''
 toHexColor(null); // ''
 toHexColor(123456); // ''
 toHexColor(0x123456123456); // ''
Parameters:
Name Type Description
stringRgb string

parentWH *
Returns:
Type
Number
