1、安裝插件程序【方正影像采集插件安裝包_I_v3.0.74.0.exe】
2、根據(jù)技術(shù)人員提供的HTMLdemo進(jìn)行開發(fā)

34.jpg

增加攝像預(yù)覽控件，客戶不需要預(yù)覽，因此我進(jìn)行了隱藏

<object id="Capture" type="application/ZCaptureVideo" hidden="hidden" />

增加按鈕事件方法，另外由于初始化需要一定的時(shí)間，技術(shù)人員說是3秒，因此我設(shè)置了一個(gè)等待3秒再執(zhí)行拍攝的方法。最后得到圖像的Base64字符流傳至后臺(tái)進(jìn)行上傳到服務(wù)器

function sleep(numberMillis) {
            var now = new Date();

        }
function onCaptureClick(event) {
            var Capture;//必須得獲取object對(duì)象
            var szDeviceIndex = "0";//設(shè)備的編號(hào)；   0：文檔攝像頭;1：人像攝像頭
