Below I will share with you an article on how to add tr to a table in angularjs. It has a good reference value and I hope it will be helpful to everyone.

Requirements:

The above is a table using a

<tr ng-repeat="rule in formData.ruleList track by $index">

Copy after login

loop show. One of the current requirements is that a field needs to be added to each row, but it cannot be displayed on the same row and needs to be displayed on the next row. I first thought of adding it directly, but there was no way to change the line. It won't do to add another one below. You can only rely on powerful angulajs and custom instructions. Let’s get started.

1 Custom instructions

.directive(
   &#39;kbnTableRow&#39;,
   function($compile) {
    return {
    restrict : &#39;A&#39;,
    link : function(scope, element) {
    element.after(&#39;<tr>&#39;);
   function expressDescHtml() {
   var detailHtml = &#39;<td></td><td colspan="5">&#39;
   + &#39;<p ng-show="rule.type!==1">&#39;
    + &#39;<p class="col-xs-9 row">&#39;
 + &#39; <input type="text" class="form-control" ng-model="rule.exprDesc"readonly ">&#39;
+ &#39;</p>&#39;
+&#39;</p>&#39; + &#39;</td>&#39;;
return detailHtml;
    }
  },
 templateUrl : &#39;libs/kbnTable/table_row/rule.html&#39;
      };
     });

Copy after login

2 rule.html is the original content

<td class="form-control-static">
 <p class="form-control-static">{{$index+1}}</p>
</td>
<td>
 <p class="form-control-static" ng-show="rule.type===1"
  style="text-align: -webkit-left;">&nbsp&nbsp&nbsp{{rule.rightVar.desc}}</p>
 <p ng-show="rule.type!==1">
  <p class="col-xs-9 row">
   <input type="text" class="form-control" ng-model="rule.rightVar.desc"
    readonly title="{{rule.rightVar.desc}}">
  </p>
  <p class="col-xs-3 ">
   <button class="btn btn-warning"
    ng-click="showRightVar(rule,&#39;rightVar&#39;)">设置</button>
  </p>
 </p>
</td>
<td class="form-control-static" ng-show="formData.execType == &#39;t02&#39;">
 <p class="form-control-static" style="padding-top: 0;">
  <input type="text" class="form-control" ng-model="rule.score"
   title="{{rule.score}}" />
 </p>
</td>
<td class="td-button" style="padding-left: 0; padding-right: 1px;">
 <button class="btn btn-danger" ng-click="del(rule)">删除</button> <input
 type="hidden" ng-model="rule.enable" />
</td>
<td class="td-button" style="padding: 8px 0;">
 <button class="btn btn-danger" ng-click="disabledRule(rule, $event)">
  <span ng-if="rule.enable == 0">启用</span> <span
   ng-if="rule.enable == 1">禁用</span>
 </button>
</td>

No need to change, just write what it was originally.

3 The tr loop part in the initial page is rewritten with our new command:

<p class="row">
   <p class="col-xs-12 row">
    <h4 class="col-xs-12">
     <b>表达式设置</b>
    </h4>
   </p>
   <p class="col-xs-12">
    <p class="row">
     <p class="col-xs-10">
      <table class="table text-center">
       <tr>
        <th ng-click="toggleAll()">
          <i class="fa discover-table-open-icon"
          ng-class="{ &#39;fa-caret-down&#39;: formData.on, &#39;fa-caret-right&#39;: !formData.on }"> 
          </i>
        </th>
        <th width="45px">序号</th>
        <th>左变量</th>
        <th>操作符</th>
        <th>右变量</th>
        <th width="75px" ng-show="formData.execType == &#39;t02&#39;">分值</th>
        <th colspan="2">操作</th>
        <th></th>
       </tr>
       <tbody>
        <tr ng-repeat="rule in formData.ruleList track by $index"
         kbn-table-row class="discover-table-row"></tr>
       </tbody>
      </table>
     </p>
     <p class="col-xs-1">
      <button class="btn btn-info" ng-click="addRule()">新增</button>
     </p>
    </p>
   </p>
