删除 node_modules操作

1.安装npm包–rimraf

npm install rimraf -g

2.在cmd指令下，进入所需删除的node_modules文件夹的位置，再输入指令

rimraf node_modules

 

window.open(location.origin + location.pathname + '#/' + item.url, '_blank')

//新开窗口下载
openwin(url) {
　　var a = document.createElement("a");
　　a.setAttribute("href", url);
　　a.setAttribute("target", "_blank");
　　a.setAttribute("id", "openwin");
　　document.body.appendChild(a);
　　a.click();
},

// 导出人员信息
exportInfo(){
　　let ids = this.selectedChangeData
　　const loading = this.$loading({
　　lock: true,
　　text: '拼命加载中',
　　spinner: 'el-icon-loading',
　　customClass: 'el-icon-loadings'
});
exportEmps(ids).then(res => {
　　let url = res.data.data
　　this.openwin(url)
}, this.err).finally(() => loading.close())
},

 

//导入人员信息

<input  ref="filElem"  type="file"  class="upload-file"  accept=".xlsx, .xls,.csv"  style="display: none"  @change="getFile"/>

<el-button type="primary" @click.native="importFile">导入</el-button>

方法:   

    importFile() {

      this.$refs.filElem.dispatchEvent(new MouseEvent("click"));

    },

    getFile() {

      let that = this;

      let param = this.$refs.filElem.files[0];

      let formData = new FormData();

      formData.append("medical_import", param);

      // this.$axios({

      //   url: "http://195.195.8.157/v3/api/medical/service/excel/import", // 请求的 url 地址

      //   method: "post", // 请求方式

      //   data: formData, // 传递的参数

      // })

      //   .then((res) => {

      //     if (res.data.code == 200) {

      //       that.$message.success(res.data.message);

      //     } else {

      //       that.$message.error(res.data.message);

      //     }

      //   })

      //   .catch((err) => {

      //     console.log(err);

      //   });

 

      this.$familyNewAddUrl

        .post("/medical/service/excel/import", formData, {

          "Content-Type": "application/x-www-form-urlencoded",

        })

        .then((res) => {

          if (res.data.code == 200) {

            that.$message.success(res.data.message);

          } else {

            that.$message.error(res.data.message);

          }

        });

    },

 

 

//滚动

var scrollHeights = obj.parents('.readItem')[0].offsetTop
obj.parents('.infor_cont_kecheng').animate({ scrollTop: scrollHeights }, 200)

var height = document.getElementsByClassName('infor_cont_wrap')[1].scrollTop

var timer = setInterval(function(){
　　height--
　　if(height == 0){
　　　　alert(11)
　　　　clearInterval(timer)
　　　　return false
　　}
　　document.getElementsByClassName('infor_cont_wrap') [1].scrollTo(0,height)

},10)

var height = document.getElementsByClassName('infor_cont_wrap')[1].scrollTop
console.log(height)
var timer = setInterval(function(){
height = height - 2
if(height < 2){
alert(11)
clearInterval(timer)
return false
}
document.getElementsByClassName('infor_cont_wrap') [1].scrollTo(0,height)

},1)

 

//大数据运用此方法去创建虚拟节点 只需要添加一次
function addSchoolNameListener() {
$('#registerPanel').on('input propertychange', '.schoolName', function() {
var name = $(this).val()
var schoolData = []
for (var i = 0, len = curSchoolList.length; i < len; i++) {
if (curSchoolList[i].itemValue.includes(name)) {
schoolData.push(curSchoolList[i])
}
}
var ul = document.getElementById('schoolList');
$('#schoolList').html('')
// 创建虚拟节点
var fragment = document.createDocumentFragment();
for (var i = 0, len = schoolData.length; i < len; i++) {
var li = document.createElement("option");
li.innerText = schoolData[i].itemValue;
fragment.appendChild(li);
}
ul.appendChild(fragment);
});
