下拉框：

 1     
 　　//反选复选框
    function queryFlowCtgy() {
 2         $.get("/flow/flowDfne/queryFlowCtgyTrees.afca", {}, function (data) {
 3             showCategory(data.data, 0);
 4             if (categoryId != null && categoryId != undefined) {//categoryId是后台返回来得值，用来设置被选项

 5 $(".category").find("option[value=" + categoryId + "]").prop("selected", true);  6  }  7 form.render(‘select‘);  8 }, "json");  9  } 10 //形成列表 11 function showCategory(data, count) { 12 $(data).each(function (i, n) { 13 var t = ""; 14 for (var j = 0; j < count; j++) { 15 t += "&nbsp;&nbsp;&nbsp"; 16  } 17 if (n.children.length > 0) { 18 $(".category").append("<option value=‘" + n.id + "‘>" + t + n.title + "</option>"); 19 showCategory(n.children, count + 1) 20 } else { 21 $(".category").append("<option value=‘" + n.id + "‘>" + t + n.title + "</option>"); 22  } 23  }); 24 form.render(‘select‘); 25 }

 1   // 点击行选中复选框
 2     $(document).on(‘click‘, ‘#pubTable  table.layui-table tbody tr‘, function () {
 3         var obj = event ? event.target : event.srcElement;
 4         var tag = obj.tagName;
 5         var checkbox = $(this).find(‘td div.laytable-cell-checkbox div.layui-form-checkbox i‘);
 6         if (checkbox.length != 0) {
 7             if (tag == "DIV") {
 8                 checkbox.click();
 9             }
10         }
11     });

$(document).on("click", "#pubTable td div.laytable-cell-checkbox div.layui-form-checkbox", function (e) {
    e.stopPropagation();
});

table 文件上传，获取文件的大小：

 1 {
 2                     field: ‘fileSize‘,
 3                     title: ‘文件大小‘,
 4                     align: ‘center‘,
 5                     templet: function (d) {
 6                         if (d.fileSize != null) {
 7                             var size = d.fileSize / 1024 * 100;
 8                             if (size > 1024) {
 9                                 size = size / 1024;
10                                 return Math.round(size) / 100 + "M";
11                             } else {
12                                 return Math.round(size) / 100 + "K";
13                             }
14                         } else {
15                             return d.fileSize;
16                         }
17                     }

对象操作：

将对象中的值保存成键值对：
  var fileLssuedLog = {};
       fileLssuedLog["hostId"] = n.hostName;
对象里面保存：键：对象
 node["resourceId"] = "task_" + (elementId);
