vue如何让自定义函数挂到全局

在main.js里进行全局注册

Vue.prototype.ajax = function (){}

在所有组件里可调用

this.ajax
实例main.js

Vue. prototype. ChangeDateFormat = function ( row, column){

// ChangeDateFormat(row, column) {

// var jsondate = row[column.property];

var jsondate = row[ column. property];

jsondate = jsondate. replace( "/Date(", ""). replace( ")/", "");

if ( jsondate. indexOf( "+") > 0) {

jsondate = jsondate. substring( 0, jsondate. indexOf( "+"));

} else if ( jsondate. indexOf( "-") > 0) {

jsondate = jsondate. substring( 0, jsondate. indexOf( "-"));

}

var date = new Date( parseInt( jsondate, 10));

var month = date. getMonth() + 1 < 10 ? "0" + ( date. getMonth() + 1) : date. getMonth() + 1;

var currentDate = date. getDate() < 10 ? "0" + date. getDate() : date. getDate();

var hour = date. getHours() < 10 ? "0" + date. getHours() : date. getHours();

var minutes = date. getMinutes() < 10 ? "0" + date. getMinutes() : date. getMinutes();

var second = date. getSeconds() < 10 ? "0" + date. getSeconds() : date. getSeconds();

return date. getFullYear() + "-" + month + "-" + currentDate + " " + hour + ":" + minutes + ":" + second;

}

index.vue

< el-table-column prop= "last_time" :formatter=" this. ChangeDateFormat" width= "200px" align= "center" label= "登陆时间" > el-table-column >
