Question

我试图在href链接上的每次点击时打开新窗口。但窗口仅替换为新页面的值，每次单击都会打开一个空白窗口。我在很多例子中都尝试了样品，但没有用。

以下是示例代码段..

var mapForm = document.createElement("form");
	    mapForm.target = "Map";
	    mapForm.method = "POST"; // or "post" if appropriate
	    mapForm.action = "../TestWindowsSample.jsp";

	    var mapInput = document.createElement("input");
	    mapInput.type = "hidden";
	    mapInput.name = "selectedId";
	    mapInput.value = selectedId;
	    mapForm.appendChild(mapInput);
	    document.body.appendChild(mapForm);

	    map = window.open("", "Map"+(windowCount++), "status=0,title=0,height=600,width=800,scrollbars=1");

	if (map) {
	    mapForm.submit();
	} else {
	    alert('You must allow popups for this map to work.');
	}

您现在只有一个目标"Map"

另外我假设selectedId和windowCount设置在其他地方，对吗？

尝试

var windowCount = 0;
var selectedId = "some string";
var mapForm;
.
.
.
mapForm = document.createElement("form");
var tgt = "Map" + (windowCount++); // define the target here
mapForm.target = tgt;
mapForm.method = "POST"; // or "post" if appropriate
mapForm.action = "http://www.zensolutions.co.nz/dev/httpdump";
var mapInput = document.createElement("input");
mapInput.type = "hidden";
mapInput.name = "selectedId";
mapInput.value = selectedId + tgt; // is this set somewhere?
mapForm.appendChild(mapInput);
document.body.appendChild(mapForm);
map = window.open("", tgt,"height=600,width=800,scrollbars"); // reuse target here
if (map) {
  setTimeout(function() { // give IE time to respond
    mapForm.submit();
  }, 10);
} else {
  alert('You must allow popups for this map to work.');
}

PS：如果您使用的是jQuery，则很容易显示div并将div的内容替换为帖子的结果。

每次点击打开新窗口的javascript代码都会替换旧窗口并创建新的空白窗口
