* @description
|
||
* The circular progress directive is used to make loading content in your app as delightful and painless as possible by minimizing the amount of visual change a user sees before they can view and interact with content.
|
||
*
|
||
* For operations where the percentage of the operation completed can be determined, use a determinate indicator. They give users a quick sense of how long an operation will take.
|
||
*
|
||
* For operations where the user is asked to wait a moment while something finishes up, and it’s not necessary to expose what's happening behind the scenes and how long it will take, use an indeterminate indicator.
|
||
*
|
||
* @param {string} md-mode Select from one of two modes: determinate and indeterminate.
|
||
* @param {number=} value In determinate mode, this number represents the percentage of the circular progress. Default: 0
|
||
* @param {number=} md-diameter This specifies the diamter of the circular progress. Default: 48
