jeecg j-dict-select-tag组件在未选择值的时候，不显示j-modal的确认按钮

KongPluginModal文件

<template>
  <j-modal
    :title="title"
    :width="width"
    :visible="visible"
    switchFullscreen
    @ok="handleOk"
    :okButtonProps="{ class:{'jee-hidden': disable} }"
    @cancel="handleCancel"
    cancelText="关闭">
    <kong-plugin-form ref="realForm" @ok="submitCallback" :disabled="disableSubmit"
                      @okButton="okButton"></kong-plugin-form>

    <!--    <template slot="footer">-->
    <!--      <a-button @click="handleCancel">取消</a-button>-->
    <!--      <a-button type="primary" @click="handleOk">确定11</a-button>-->
    <!--    </template>-->

  </j-modal>
</template>

重点为
:okButtonProps="{ class:{‘jee-hidden’: disable} }"
和@okButton=“okButton”

data中  disable: true
method中      okButton(res) {
                //确定是否显示表单的确认按钮
                this.disable = res
              }

KongPluginForm

<template>
  <a-spin :spinning="confirmLoading">
    <j-form-container :disabled="formDisabled">
      <a-form :form="form" slot="detail">
        <a-row>
          <a-col :span="24">
            <a-form-item label="插件名" :labelCol="labelCol" :wrapperCol="wrapperCol">
              <j-dict-select-tag
                v-decorator="['name', { rules: [{ required: true, message: '请选择插件' }] }]"
                :triggerChange="true"
                placeholder="请选择插件"
                dictCode="kong_plugin_name"
                @change="getType"
              />
            </a-form-item>
          </a-col>

重点：@change=“getType”

data中  pluginName: ''
method中  	//当切换plugin类型的时候,得到他的值
            getType() {
                this.$nextTick(() => {
                    console.log('form:{}', this.form.getFieldValue('name'));
                    if (typeof this.form.getFieldValue('name') == 'undefined' || JSON.stringify(this.form.getFieldValue('name')) == "{}") {
                        //没有选择插件类型名的话，禁掉提交功能
                        this.$emit('okButton', true)
                    } else {
                        this.$emit('okButton', false)
                    }
                });
            },
