使用键盘上的Enter来激活函数ionic3

Question

我想使用手机上的输入键盘按钮搜索项目。红色链接上有过滤功能，当您按下移动设备上的输入/搜索按钮时，我也想要触发。怎么做？

Answer 1

您可以使用data <- read.table(text = " Clients Throughput Systems Error 250 2494 Za 72.986 500 2491 Za 104.854 750 401 Za 130.034 1000 0 Za 0 1250 0 Za 0 250 2501 ZCT 58.987 500 2499 ZCT 89.927 750 2380 ZCT 130.475 1000 2321 ZCT 139.450 1250 2296 ZCT 142.580", header = TRUE) plot1 <- ggplot(data=data , aes(x=Clients, y=Throughput, group=Systems, colour = Systems, shape=Systems)) + geom_errorbar(aes(ymin=Throughput-Error, ymax=Throughput+Error), width=20.5, colour="black") + geom_line(size=1.2) + geom_point(size=2.3) plot1 <- plot1 + scale_y_continuous(breaks= seq(0,3000,500), limits = c(0,3000)) + labs(x="Number of clients") + scale_x_continuous(breaks = c(250,500,750,1000,1250)) + labs(y="Throughput (abds/sec)") plot1 <- plot1 + scale_colour_manual(values=c("#00ff00","#0000ff")) plot1 <- plot1 + theme_bw() + theme(legend.position="bottom") + labs(fill="", colour=" ", shape=" ") + theme(text = element_text(size=18)) + guides(fill = guide_legend(keywidth = 0.8, keyheight = 0.01))+ annotate("Text", x=data$Clients[data$Throughput==0], y=data$Throughput[data$Throughput==0], label="X", size=6) plot1 检测按下Enter按钮。

(keyup.enter)

并在您的<ion-input type="text" (keyup.enter)="onEnter()"></ion-input> 文件中，您可以处理该事件
