关于前端:elementui-elinput-无法使用-vmodel修饰符

应用blur办法在失去焦点时进行trim（）

<el-form    ref="form"    :model="formData"    :rules="formRules"    style="width:80%;margin-top:20px;"    size="small"    label-width="100px">    <el-form-item label="以后节点" prop="moduleId">        <el-input         readonly        v-model="formData.moduleId"         @blur="formData.moduleId=$event.target.value.trim()"        ></el-input>    </el-form-item>    <el-form-item label="帮忙URL">        <el-input         placeholder="帮忙URL"        @blur="formData.helpUrl=$event.target.value.trim()"        v-model="formData.helpUrl"></el-input>    </el-form-item>    <el-form-item label="模块形容">        <el-input         type="textarea"         placeholder="编辑模块形容..."        @blur="formData.moduleDesc=$event.target.value.trim()"        v-model="formData.moduleDesc"></el-input>    </el-form-item>    <el-form-item v-if="control.save">        <el-button type="primary" @click="save">保留</el-button>    </el-form-item></el-form>
