javascript - 如何在单引号之间添加两个变量

Question

我有

function delImage(posteId,imagebinId) { 
    $.get("<?php  echo base_url('/Home/deletePostimage/') ?>"); 

    return false; 
} 

我想要像/Home/deletePostimage/posteId/imagebinId

我试过了

$.get("<?php  echo base_url('/Home/deletePostimage/')+posteId+"/"+imagebinId ?>"); 

但是它将两个数字相除

喜欢 posteId=5 imagebinId =2

结果将是

/Home/deletePostimage/2,5

来自

的参数

<a class="postimgsd" onClick="if(confirm('Are you sure you want to delete this image ?')){delImage(<?php echo $value['id'],$get_images[0]['binId']; ?>); rmItem(<?php echo $i; ?>);}else{} ;  " >

Answer 1

使用 ES6，您可以使用 string interpolation 来做到这一点:

$.get(`<?php  echo base_url('/Home/deletePostimage/${postId}/${imagebinId}') ?>`);

没有ES6，还有另一个answer回答这个问题，或者使用这个:

var url = '/Home/deletePostimage/' + postId + '/' + imagebinId;
$.get("<?php  echo base_url('" + url + "') ?>");

此外，调用该函数的代码实际上应该是:

<a class="postimgsd" onClick="checkDeletion()" />

<script type='text/javascript'>
    function checkDeletion() {
        if(confirm('Are you sure you want to delete this image ?')) {
            var postId = <?php echo $value['id']; ?>;
            var imagebinId = <?php echo $get_images[0]['binId']; ?>;
            delImage(postId, imagebinId);
            rmItem(<?php echo $i; ?>);
        }
    }
</script>
