The currentForecast variable is set to the first item in the array; this is the object displayed by the EditForm. The user can cycle through the array using the numeric input field above the EditForm on the page. This field's value is used as an index of the array, an...

Looking at another approach, I thought that since my code parses the input commands into an array of INPUT structures to pass to SendInput, I might be able to spin through the array one at a time and do extra pauses on the mouse events. The question of how long to wait became an exp...
//data: data () { return { scrollY:Number, foodTops:Array, current:Number } } --- //watch: watch:{ scrollY:function(){ this.current = this.foodTops.find((top)=>{ return top >= this.scrollY }) } } 思路:设置一个计算方法,让index===current()的时候给对应的index增加current类名 ...

To individually drive each diode for full control of effects requires PWM channels, which EBV has implemented in an Altera MAX II EPM 1270 Complex Programmable Logic Device (CPLD). The MAX II chip suits the application due its input/output pins. The logic on the CPLD implements the Pulse ...
