我有三个div，如何仅在特定的div中加载数据而不重新加载php-codeigniter中的整个页面？

Question

我有三个div标签，单击链接后，我只想在第二个div中加载数据而不加载整个页面，我想将第一个和第三个div保持为静态，第二个div应该是动态的？

   <div class="first">

   <a href="patientLogin/patientVisit_details/<?php echo $data->patient_visit_id;?>"><?php echo $data->hospital_name;?></a>

   </div>


   <div class ="second">
   //content//
   <div>


   <div class ="third">
   //content//
   <div>

只是试图返回，你从所需要的值ajax function.Something这样可能do.Soppose你有insert.php文件，你可以echo or return的data在结束function需要被填充到页

$('.first a').click(function(){
    $.ajax({
        type: "POST",
        url: "insert.php",
        cache: false,
        success: function(data){
                 //Now you have obtained the data that was was returned from the function
                 //if u wish to insert the value into an input field try
               $('.second').html(data); //now the data is populated in the input field 

         }
        });
})

您可以通过ajax实现这些目标。

1) As you want to apply dynamic data loading on some click event of some anchor link then please don't apply anchor link as:
"<a href="patientLogin/patientVisit_details/<?php echo $data->patient_visit_id;?>"><?php echo $data->hospital_name;?></a>" the anchor leads you to the href value link. alternatively you can do like (<a href="javascript:void(0);">);

现在就您的CI而言； 鉴于：

<a href="javascript:void(0);"onclick="javascript:changeData('<?php echo $data->patient_visit_id;?>')"><?php echo $data->hospital_name;?></a>

在Js文件中

function changeData(parentVisitId){

 var urlCI = 'patientLogin/patientVisit_details/'+parentVisitId;

 $.ajax({
        type: "GET",
        url: urlCI,
        data:{
            'parenIdIfReq':parentVisitId,
        },
        success: function(response) {
            if(response!=''){
                $('.second').html(response);
            }
            else{
                return false;
            }
        }
    });

}
In controller/action i.e patientLogin/patientVisit_details/parentVisitedId
 function patientVisit_details($parentVisiteId){
    echo "whatever data you want to return as response";
 }
