@H_618_2@现在我只是制作一个图像路径来显示它
@H_618_2@更新
@H_618_2@脚本：
$("body").on("change",function(data) {
//add content insIDe that
$(".casTing_details [data-index= " + index + "]").HTML(`
<div class="d-flex flex-row mb-3 ">
<a class="d-block position-relative" href="#">
<img src={{ URL::to('/') }}/casTingimages/" + $casTings->photo} + " class="List-thumbnail border-0" />
<span
class="badge badge-pill badge-theme-2 position-absolute badge-top-right">NEW</span>
</a>
</div>`); //data
//});
})
});
public function getCasTing()
{
$ID_casTing = request('ID_casTing');
$casTings = CasTing::where('ID_casTing',$ID_casTing)->get();
return vIEw('Projet.ajout_projet')
->with('casTings',$casTings);
}
jquery-3.3.1.min.Js:2 GET http://localhost:8000/getCasTing/16 404 (Not Found)
