uniapp切换背景色和字体颜色
uniapp不支持原生js的节点操作,应使用三元运算符代码如下:
一、建议使用
<u-col :style="{height:60+'px',backgroundColor:flage?'#00a49b':'#cdedea',color:flage?'#ffffff':'#43c5a9'}" :span="6"
align="center" justify="center" @tap="tabColor('1')" textAlign="left">
本月统计:12560
<u-col :span="6" :style="{height:60+'px',backgroundColor:flageB?'#00a49b':'#cdedea',color:flageB?'#ffffff':'#43c5a9'}"
align="center" justify="center" @tap="tabColor('2')" textAlign="left">
上月统计:10160
export default {
data() {
return {
title: 'Hello',
backG:'#cdedea',
backGB:'#00a49b',
flage:true,
flageB:true,
}
},
onLoad() {
this.tabColor(1)
},
methods: {
tabColor(key){
if(key=='1'){
this.flage =false;
this.flageB= true;
}else{
this.flageB =false;
this.flage= true;
}
}
二、没有使用组件开发时可以使用$refs,使用了某些组件真机不支持
// tabColor(key) {
// const that = this;
// that.$refs.backG.$el.style.backgroundColor="";
// that.$refs.backG.$el.style.color = "";
// that.$refs.backGB.$el.style.backgroundColor = "";
// that.$refs.backGB.$el.style.color = "";
// if (key == 1) {
// that.$refs.backG.$el.style.backgroundColor = "#cdedea";
// that.$refs.backG.$el.style.color = "#43c5a9";
// that.$refs.backGB.$el.style.backgroundColor = "#00a49b";
// that.$refs.backGB.$el.style.color = "#ffffff";
// }else{
// that.$refs.backGB.$el.style.backgroundColor = "#cdedea";
// that.$refs.backGB.$el.style.color = "#43c5a9";
// that.$refs.backG.$el.style.backgroundColor = "#00a49b";
// that.$refs.backG.$el.style.color = "#ffffff";
// }
// }
三、原生js(真机运行不支持)
// tabColor(key) {
// var bt1 = document.getElementById('backG');
// var bt2 = document.getElementById('backGB');
// bt1.style.backgroundColor = "";
// bt1.style.color = "";
// bt2.style.backgroundColor = "";
// bt2.style.color = "";
// if (key == 1) {
// bt1.style.backgroundColor = "#cdedea";
// bt1.style.color = "#43c5a9";
// bt2.style.backgroundColor = "#00a49b";
// bt2.style.color = "#ffffff";
// } else {
// bt2.style.backgroundColor = "#cdedea";
// bt2.style.color = "#43c5a9";
// bt1.style.backgroundColor = "#00a49b";
// bt1.style.color = "#ffffff";
// }
// }
}
