自己最近寫了一個(gè)網(wǎng)頁(yè)多圖上傳的腳本,感覺挺實(shí)用的,細(xì)節(jié)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(dá)到自己的需求,如果說圖片點(diǎn)擊沒反應(yīng),別忘了加入jquery
