vue定义全局过滤器

新建承载过滤器的文件filters.js

var fileToUrl = function (val) {
  
    return val;
}

var timeFormat=function(time,fmStr){
    fmStr=fmStr||"yyyy-mm-dd hh:MM:ss"
    const weekCN = '一二三四五六日';
    const weekEN = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday'];
    console.log(typeof time)
    if(typeof time=="number"){
        time=new Date(time)
	}
	if(!time){
		return "";
	}
	let year = time.getFullYear();
	let month = time.getMonth() + 1;
	let day = time.getDate();
	let hours = time.getHours();
	let minutes = time.getMinutes();
	let seconds = time.getSeconds();
	let milliSeconds = time.getMilliseconds();
	let week = time.getDay();
    console.log(fmStr)

    }

	fmStr = fmStr.replace('w', week);

}

export {
    fileToUrl,
	timeFormat
}

min.js引入

import * as filters from './plugins/filters.js'
Object.keys(filters).forEach(key => {
  Vue.filter(key, filters[key])
})

vue页面中可直接使用

{{contract.createDate | timeFormat("yyyy-mm-dd") }}
