排序，splice会改变数组长度，for循环不好使，splice不会改变数组长度，但是第二个参数要求是下标--
var temparrarr1 = []
            var temparrarr2 = []

            temparrarr1 = this.recOrderInfo.filter(function (item) {
              return item.youxianji.match(/加急/)
            })
            temparrarr2 = this.recOrderInfo.filter(function (item) {
              return !item.youxianji.match(/加急/)
            })

            this.recOrderInfo = temparrarr2.concat(temparrarr1)

===============================

tp3 会先 show column
过滤不存在的查询字段
所以看到查询字段不出现，多半是字段不存在

<script type="x-template" id="dddaaasss">
<div>
<Button type="primary" @click="modal1 = true">Display dialog box</Button>
<Modal
v-model="modal1"
title="Common Modal dialog box title"
@on-ok="ok"
@on-cancel="cancel">
<p>Content of dialog</p>
<p>Content of dialog</p>
<p>Content of dialog</p>
</Modal>
</div>
</script>
写js的html模板但是又不会被解析的办法

“推荐第四种写法，x-template”
<if condition="$Think.session.userInfo.usertype eq 1 ">style="display:none;"</if>

tp3.2的条件渲染 v-if v-else

displaynone 和 visibility 要直接加在tr上，外面包的div不起作用
linux严格区分文件大小写，windows不是

tp3 api tp5 api
统计数组内出现的次数
splice
split
replace
search
``
v-model

================

$begindate = date("Y-m-d H:i:s",mktime(0, 0 , 0,date("m"),1,date("Y")));
            $enddate = date("Y-m-d H:i:s",mktime(23,59,59,date("m"),date("t"),date("Y")));
