vue + element 关于 type = number 防止鼠标滚轮改变数字

1.使用一下时间

@mousewheel.native.prevent
@DOMMouseScroll.native.prevent

2.具体使用

<el-form-item label="" label-width="0" class="m-px-b-0" prop="planNumber">
<el-input
    v-model="scope.row.planNumber"
    oninput="if(isNaN(value)) {value = parseFloat(value)}if(value < 0){value = 0}
        if(value.indexOf('.') == -1 && value.length > 5) {value=value.slice(0,5)}
        if(value.indexOf('.') >= 5) {
                    value=value.slice(0,5) +value.slice(value.indexOf('.'),value.indexOf('.')+0)}
        if(value.indexOf('.') > -1 && value.indexOf('.') <= 5) {
                    value=value.slice(0,value.indexOf('.')) +
                        value.slice(value.indexOf('.'),value.indexOf('.')+0)}
        if(value.indexOf('0') == 0) {value=value.slice(1)}"
    placeholder="请输入年度计划任务数"
    :controls="false"
    type="number"
    @mousewheel.native.prevent
    @DOMMouseScroll.native.prevent
></el-input>
<span v-else class="ellipsis-1">{{ form.planNumber }}</span>
</el-form-item>
