我在 jsp 表单中有两个单选按钮(遍历和直接)。遍历用于正常提交表单,直接用于使用 iframe 提交表单。使用 iframe 提交表单后,如果我尝试正常提交,则应用程序正在新打开window.如何防止表单在新窗口中打开。
function submitAction() {
var fileValue = document.getElementById("file1").value;
if (fileValue == "") {
alert("Please uploaded file type of .war or .html type");
return false;
}
var valuePassed = getCheckedRadio();
var url="uploadfile.do?rad=" + valuePassed;
if (valuePassed == "traverse") {
document.EntryForm.action = url;
document.EntryForm.submit(); //Normal way of submitting.
}else if (valuePassed == "direct") {
alert("direct");
url=url+"&fileName="+fileValue;
directConvert(document.EntryForm,url,'downloaddiv'); }
}
function directConvert(form, action_url, div_id){
// Create the iframe...
var iframe = document.createElement("iframe");
iframe.setAttribute("id", "upload_iframe");
iframe.setAttribute("name", "upload_iframe");
iframe.setAttribute("width", "0");
iframe.setAttribute("height", "0");
iframe.setAttribute("border", "0");
iframe.setAttribute("style", "width: 0; height: 0; border: none;");
// Add to document...
form.parentNode.appendChild(iframe);
//window.frames['upload_iframe'].name = "upload_iframe";
iframeId = document.getElementById("upload_iframe");
// Add event...
var eventHandler = function () {
if (iframeId.detachEvent) iframeId.detachEvent("onload", eventHandler);
else iframeId.removeEventListener("load", eventHandler, false);
// Message from server...
if (iframeId.contentDocument) {
content = iframeId.contentDocument.body.innerHTML;
} else if (iframeId.contentWindow) {
content = iframeId.contentWindow.document.body.innerHTML;
} else if (iframeId.document) {
content = iframeId.document.body.innerHTML;
}
document.getElementById(div_id).innerHTML = content;
// Del the iframe...
setTimeout('iframeId.parentNode.removeChild(iframeId)',50);
}
if (iframeId.addEventListener) iframeId.addEventListener("load", eventHandler, true);
if (iframeId.attachEvent) iframeId.attachEvent("onload", eventHandler);
// Set properties of form...
form.setAttribute("target", "upload_iframe");
form.setAttribute("action", action_url);
form.setAttribute("method", "post");
form.setAttribute("enctype", "multipart/form-data");
form.setAttribute("encoding", "multipart/form-data");
form.submit();
}
当我第一次尝试遍历时,它工作正常,但通过 iframe 提交后,如果我尝试遍历,它会在新窗口中打开。如何防止它在新窗口中打开。
