如何将id从javascript传递到codeigniter中的引导模型？

Question

我将一个值id传递给javascript函数。这里的id正在打印。

<script> 
    function openModal(id) { 
    document.getElementById('myModal').style.display = "block"; 
    var img_id = id; 
    document.getElementById('caption').innerHTML = img_id; 
    } 
</script> 

现在我想将这个值传递给引导模式

<div id="myModal" class="modal"> 
    <button type="button" id="close" onclick="closeModal()">close</button> 

    <div class="modal-content"> 
    <div class="mySlides"> 

    <?php  

    //here i want to use this id with if condition so that desired image is 
    //displayed.With for each all images are coming. 
    //$project_images = explode(",", $value['project_gallery']); 

    $project_images = json_decode($value['project_gallery'],true); 

    foreach ($project_images as $project_image_value) { 
    ?> 

    <img src="<?= base_url() ?>assets/uploads/projects/<? =$project_image_value['fname']?>" style="width:100%"> 

    <?php 
    } 
    ?> 
    </div> 
</div> 
</div> 

是有可能。如果真让我知道。

Answer 1

在引导模式添加一个隐藏字段像

<input type="hidden" id="img_id" name="img_id"> 

，并添加脚本

function openModal(id) { 
$("#img_id").val(id); 
document.getElementById('myModal').style.display = "block"; 
var img_id = id; 
document.getElementById('caption').innerHTML = img_id; 

}

因此，在模型你要通过

值为1个的场img_id
