我正在尝试在标签输入文本字段中添加弹出窗口工具提示。但是它不起作用。 这是我的代码:
<div class="form-group"><!-- form-group -->
<div class="col-lg-6" id="prefix_value_div_error" style="display:none">
<?php echo $form->labelEx($model,'prefix_value', array('class'=>'col-lg-4 control-label')); ?>
<div class="col-lg-7">
<?php echo $form->textField($model,'prefix_value',array('class'=>'form-control tagsinput popovers','id'=>'prefix_value',"data-placement"=>"top","data-content"=>Yii::t('app','model.callThresholdPlanMaster.prefix_value.desc') ,"data-trigger"=>"hover", "data-original-title"=>Yii::t('app','model.callThresholdPlanMaster.prefix_value'))); ?>
<div id="prefix_value_error">
<?php echo $form->error($model,'prefix_value'); ?>
</div>
</div>
</div>
</div>
