2.模态框登录

一、message弹框延时修改

this.$message({
     message:res.data.msg,
     duration:1000,
     type:'success'
})
type    主题    string    success/warning/info/error    info

二、对话框实现登陆模块

status-icon 提示图标
rules  验证规则

 <el-button  @click="dialogFormVisible = true" >登录</el-button>
      <el-dialog title="登陆界面" :visible.sync="dialogFormVisible">
        <el-form :model="form"  status-icon :rules="rules">
          <el-form-item label="用户名"  prop="username" :label-width="formLabelWidth">
            <el-input v-model="form.username" ></el-input>
          </el-form-item>
          <el-form-item label="密码" prop="pass" :label-width="formLabelWidth">
            <el-input type="password" v-model="form.pass"> </el-input>
          </el-form-item>
        </el-form>
        <div slot="footer" class="dialog-footer">
          <el-button @click="dialogFormVisible = false">取 消</el-button>
          <el-button type="primary" @click="handleLogin">确 定</el-button>
        </div>
</el-dialog>

export default {
  data() {
    var validatePass = (rule, value, callback) => {
      if (value === "") {
        callback(new Error("请输入密码"));
      }
    };
    return {
      dialogFormVisible: false,
      form: {
        username: "",
        pass: ""
      },
      rules: {
        pass: [{ validator: validatePass, trigger: "blur" ,required:true}],
        username: [  { required: true, message: '请输入活动名称', trigger: 'blur' }]
      },
      formLabelWidth: "120px"
    };
  },
  methods:{
    handleLogin(){
      console.log(this.form)    //可以取到form里面的所有东西
    }
};
</script>
