在项目开发过程中,处理输入框的数据时,不可避免的会有一些禁止输入的需求,例如禁止输入空格,只允许输入数字、汉字或者禁止输入特殊字符等。使用惯了原生js的开发时,再使用element UI会发现以前的写法不起作用了,后来在网上搜索,发现实现方式略有不同,需要加一下特定的修饰符。在处理input框禁止输入空格时,实现方法,...

Figure 4-2. XOR Venn diagram XOR has some nifty applications in computer graphics and finding overflows (math errors). You can also toggle our LED on and off using XOR: register = register ^ (1 << 2); Note that (1 << 2) would always be a 1 in the table. If it is I...
Figure 32. Typical Connection Diagram ANALOG INPUT Single-Ended Inputs The AD7327 has a total of eight analog inputs when operating the AD7327 in single-ended mode. Each analog input can be independently programmed to one of the four analog input ranges. In applications where the signal ...
Block Diagram of Video Processor Figure 12 shows a block diagram of the ADV7182A video processor. The ADV7182A can handle standard definition (SD) video in CVBS, Y/C, and YPrPb formats. The video processor features luminance and chrominance paths. If the input video is a composite type (...
2.1 Advantage of using two comparators The purpose of using the second comparator (comp2) can be understood from the diagram below (Figure 2), which shows the relationship between the op-amp output (Amp in Figure 1: Circuit diagram on page 6) a...
