Javascript图像onLoad

Question

为什么onLoad没有被触发？

      function FULL_IMAGE(fimage){
        document.getElementById("FULL_SRC").onLoad = function(){
          offsetTop = document.getElementById("FULL_SRC").height / 2;
          offsetLeft = document.getElementById("FULL_SRC").width / 2;
          document.getElementById("FULL_SRC").style.marginTop="-"+offsetTop+"px";
          document.getElementById("FULL_SRC").style.marginLeft="-"+offsetLeft+"px";
        }
        document.getElementById("FULL_SRC").src=fimage;
        document.getElementById("FULL_VIEW").style.display="block";
      }

Answer 1

有时当从浏览器缓存中检索图像时,onload事件不会被触发,因此你可能会做一些小问题:

function FULL_IMAGE(fimage) {
    var loaded = false;
    function loadHandler() {
        if (loaded) {
            return;
        }
        loaded = true;
        /* your code */
    }
    var img = document.getElementById('FULL_SRC');
    img.addEventListener('load', loadHandler);
    img.src = fimage;
    img.style.display = 'block';
    if (img.complete) {
        loadHandler();
    }
}

在我的原始代码中,我onLoad没有使用onload...第二行代码应该读取

document.getElementById("FULL_SRC").onload = function(){

用小写的" l" onload.
