功能需求:
列表进行批量查询,需要对输入的值做提交校验,分三种情况:
若部分字符串有误,部分字符串需要变更字体颜色做提示,再次点击确认则对部分正确数据执行批量查询
若全部数据有误则变更字体颜色做提示,再次点击确认查询为空
若全部数据正确则直接执行批量查询
需要变更字体颜色做提示的情况分三种:一种为重复数据
一种为未通过校验数据
一种为既没有通过校验又重复的数据
知识点:
contenteditable:contenteditable为true可编辑元素内容
实现:
html
<el-button type="primary" :size="$formSize" @click="handleBatchQuery">批量查询</el-button>
<!--批量查询-->
<el-dialog title="批量查询" :visible.sync="batchQuery" width="600px">
<div v-if="batchQuery" id="editor" class="editor" ref="editor" contenteditable="true" @click="showInput=true">
<span v-if="!showInput" class="uninput">
手动输入多个ICCID或设备id,以换行符分隔,如:<br/>
94816c8ded8f<br/>
94816c8ded8f
</span>
</div>
<div slot="footer" class="dialog-footer">
<el-button @click="cancelQuery">取消</el-button>
<el-button type="primary" @click="submitQuery">确定</el-button>
</div>
</el-dialog>

css
.editor{
width: 100%;
height: 150px;
overflow: auto;
border: 1px solid #dcdfe6;
}
.uninput{
color: #dcdfe6;
color: #c0c4cc;
line-height: 20px;
}
效果:
当文字颜色变更提示后,再次点击确认后只会查询正确的(包含数据重复的)数据
