本文实例为大家分享了javascript自定义加载loading效果的具体代码,供大家参考,具体内容如下

加载中图片,底色为白色(看不到)

效果如图:

使用方法


this.tool.showLoading('加载中', this)
this.tool.showLoading('合成中', this)

this.tool.hideLoading()

引用文件

在App.vue中


<style scoped>
@import './common.css';
</style>

在main.js中


import tools from './tools'
Vue.prototype.tool = tools

tools.js


export default {
//显示加载框---使用方法,例如:this.tool.showLoading('正在加载',this,'1')
showLoading (message, el, type) {
var html = '';
html += '<i class="mui-spinner mui-spinner-white"></i>';
html += '<p class="text">' + (message || "数据加载中") + '</p>';

//遮罩层
var mask = document.getElementsByClassName("mui-show-loading-mask");
if (mask.length == 0) {
mask = document.createElement('div');
mask.classList.add("mui-show-loading-mask");
// console.log(type)
// 自己添加内容...start
if (type !== '2' && type) {
var winHig = document.documentElement.clientHeight;
if (el.$refs.nav) {
var heightNav = el.$refs.nav.offsetHeight;
var heightFix = el.$refs.fixed.offsetHeight;
if (type === '1') {
var loHig = winHig - heightNav - heightFix + 'px'
} else {
loHig = winHig - heightFix + 'px'
}
mask.style.top = heightFix + 'px'
mask.style.height = loHig
}
}
// 自己添加内容...End
document.body.appendChild(mask);
mask.addEventListener("touchmove", function (e) { e.stopPropagation(); e.preventDefault(); });
} else {
mask[0].classList.remove("mui-show-loading-mask-hidden");
}
//加载框
var toast = document.getElementsByClassName("mui-show-loading");
if (toast.length == 0) {
toast = document.createElement('div');
toast.classList.add("mui-show-loading");
toast.classList.add('loading-visible');
document.body.appendChild(toast);
toast.innerHTML = html;
toast.addEventListener("touchmove", function (e) { e.stopPropagation(); e.preventDefault(); });
} else {
toast[0].innerHTML = html;
toast[0].classList.add("loading-visible");
}
},

//隐藏加载框----使用方法,例如:this.tool.hideLoading();
hideLoading (callback) {
var mask = document.getElementsByClassName("mui-show-loading-mask");
var toast = document.getElementsByClassName("mui-show-loading");
if (mask.length > 0) {
mask[0].classList.add("mui-show-loading-mask-hidden");
}
if (toast.length > 0) {
toast[0].classList.remove("loading-visible");
callback && callback();
}
}
