javascript等待 [英] javascript wait

问题描述

我已经收集到javascript没有方便的wait（）函数，所以

我做了以下函数makeDelay（）来利用PHP的sleep（） ，

然后等待，并以完成回复...我的问题是

，javascript不等待makeDelay（秒）到完成......？


makeDelay（5）;

iDontWaitForNobody（）;


函数makeDelay（秒）{


url =" make_delay.php？delay =" +秒;

http.open（" GET"，url，true）;


loadStatus = document.getElementById（" loadStatus"）;


http.onreadystatechange = function（）{

if（http.readyState == 1）{

loadStatus.src =" ; balls / load1.gif" ;;

}

if（http.readyState == 2）{

loadStatus.src =" balls /load2.gif" ;;

}

if（http.readyState == 3）{

loadStatus.src =" balls / load3 .gif" ;;

}

if（http.readyState == 4）{

if（http.responseText ==" done" ）

不要这样做。

使用setTimeout（）;


case：

setTimeout（" iDontWaitForNobody（）"，5000）;

在此case：

setTimeout（" iDontWaitForNobody（）"，5000）;

甚至只是


setTimeout（iDontWaitForNobody，5000）;

I''ve gathered that javascript doesn''t have a handy wait() function, so
I made the following function makeDelay() to make use of PHP''s sleep(),
which then does the waiting, and responds with "done"...my problem is
that the javascript doesn''t wait for makeDelay(seconds) to finish...?

makeDelay(5);
iDontWaitForNobody();

function makeDelay(seconds) {

url="make_delay.php?delay=" + seconds;
http.open("GET",url,true);

loadStatus=document.getElementById("loadStatus");

http.onreadystatechange=function() {
if (http.readyState==1) {
loadStatus.src="balls/load1.gif";
}
if (http.readyState==2) {
loadStatus.src="balls/load2.gif";
}
if (http.readyState==3) {
loadStatus.src="balls/load3.gif";
}
if (http.readyState==4) {
if(http.responseText == "done")
loadStatus.src="balls/load0.gif";
}
}
http.send(null);
}

Don''t do that.
Use setTimeout();

In this case:
setTimeout("iDontWaitForNobody()",5000);

Don''t do that.
Use setTimeout();

In this case:
setTimeout("iDontWaitForNobody()",5000);

or even just

setTimeout(iDontWaitForNobody, 5000);
