自己最近寫了一個網頁多圖上傳的腳本,感覺挺實用的,細節就不要說了,直接貼代碼了~
<head><style>.pro_img{ margin-left:10px;margin-top:10px;width:300px;height: 300px;background-color: black; --border-radius:999em; overflow:hidden;float:left ; --margin:5% 35%;position: relative;}.pro_img img{ position: absolute;left: 50%;top:50%; transform: translate(-50%,-50%);width: 100% }.pro_img {position:relative}.pro_img input{position: absolute;width: 100%;height: 100%;margin:0;opacity:0;z-index: 100;}</style><script type=text /javascript src=jquery.min.js></script><script>name_pic=1;function t1(o){//alert(name_pic); if(o==1 || name_pic!=1){ var file =file+o; var img=img+o; var hid=hidden+o; var aa=a+o; }else{ var file=file+name_pic; var img=img+name_pic; var hid=hidden+name_pic; var aa=a+name_pic; } var docObj = document.getElementById(file); var imgObjPreview = document.getElementById(img); var hidden=document.getElementById(hid); // alert(hidden); if (docObj.files && docObj.files[0]) { hidden.src=window.URL.createObjectURL(docObj.files[0]); //獲取file文件的路徑hidden.onload=function(){ var width=hidden.width; var height=hidden.height; var a=document.getElementById(aa); if(width>height){ imgObjPreview.style.cssText='width:100%'; //重寫css樣式}else{ imgObjPreview.style.cssText ='height:100%;width:auto;'; } imgObjPreview.src = window.URL.createObjectURL(docObj.files[0]); imgObjPreview.style.display = 'block'; } }else{ return false; } if(o==name_pic){ var count=$('.pro_img').length; if(count<6){ name_pic++; var pic_div=<a class='pro_img' id='a+name_pic+' ><input type='file' id='file+name_pic+' accept='image/*' multiple='multiple' name='pic[]' onchange='t1(+name_pic+)'/><img src='upload.jpg ' id='img+name_pic+'></a><img id='hidden+name_pic+' style='display:none;'>; $('#upload').append(pic_div); } }}</ script></head><!-- multiple='multiple' --><form action=http://192.168.0.7/index.php/Home/Pic/upload enctype=multipart/form-data method=post> <div id='upload'><a class='pro_img' id='a1' ><input type='file' id='file1' accept='image/*' multiple='multiple' name='pic[ ]' onchange='t1(1)'/><img src='upload.jpg' id='img1'></a><img id='hidden1' style='display:none;'></div ><input type='submit' value=上傳/></form>自己替換一些upload.png這張圖片就能達到自己的需求,如果說圖片點擊沒反應,別忘了加入jquery
以上所述是小編給大家介紹的基於HTML實現多圖上傳預覽功能，希望對大家有所幫助，如果大家有任何疑問請給我留言，小編會及時回復大家的。在此也非常感謝大家對VeVb武林網網站的支持！
