模板引擎 laytpl

<div id="cont" class="layui-row layui-col-space15"></d><script id="demo" type="text/html"> // 模板{{# layui.each(d.list, function(index, item){ }}<strong>{{= item.modname}}</strong>
<strong>{{= item.alias}}</strong>
<strong>{{= item.site}}</strong>{{# }); }}{{# if(d.list.length === 0){ }}无数据{{# } }}</script><script>
var laytpl = layui.laytpl;
var data = {"title": "Layui 常用模块","list": [{"modname": "弹层","alias": "layer","site": "layer.domain.com"},{"modname": "表单","alias": "form"},{"modname": "表格","alias": "table"},{"modname": "日期","alias": "laydate"},{"modname": "上传","alias": "upload"}]
};var getTpl = demo.innerHTML,view = document.getElementById('cont');laytpl(getTpl).render(data, function(html) {view.innerHTML = html;});
<script>

Ajax 读取json 数据

var $ = layui.jquery; // layui 内含jquery$.ajax({type:"get", // post 还get 传url:"./softall.json",data:{},dataType:"json", // 数据类型success:function(data){ // 成功返回函数console.log(data);});}});

筛选数组 filter

var da = data.list;
// 提取json 数据数组出
let hm = da.filter(function(item){return item.lb == "电脑维护";
});
//筛选 lb = 电脑维护 的数组
data.list = hm;
// 再将数据放入json 数据里 完成筛选

css 限制文体显示过长用。。。代替

           <style>.limit-text {  /* 限制文件显示长度 */width: 150px; /* 显示150px文本其余用... */white-space: nowrap;overflow: hidden;text-overflow: ellipsis;}</style><p class="layadmin-textimg limit-text">limit-text

模板引擎json数据转入表格组件json 使用

{"title": "Layui 常用模块","list": [{"modname": "弹层","alias": "layer","site": "layer.domain.com"},{"modname": "表单","alias": "form"}]
}转成 表单的就这样{"code": 0,  // 加入"msg": "",  // 加入"count": 1000, // 加入"title": "Layui 常用模块","list": [                      // "data" 无法加入，到时在 表格js 加 parseData 处理{"modname": "弹层","alias": "layer","site": "layer.domain.com"},{"modname": "表单","alias": "form"}]
}

js代码处理：

table.render({elem: '#LAY-index-topSearch',url: '../../software/softall.json' //模拟接口,parseData: function(res){ return {"code": 0, // 解析接口状态"msg": "", // 解析提示文本"count": 15, // 解析数据长度"data": res.list // 解析数据列表};},page: true

用json数据时 table组件分页失败的处理方法

// table里加入这些代码,parseData: function(res) { // 将数据解析成 table 组件所规定的数据，res为从url中get到的数据var result;console.log(this);console.log(JSON.stringify(res));if (this.page.curr) {result = res.data.slice(this.limit * (this.page.curr - 1), this.limit * this.page.curr);} else {result = res.data.slice(0, this.limit);}return {"code": 0, //解析接口状态"msg": res.msg, //解析提示文本"count": res.count, //解析数据长度"data": result //解析数据列表};}
