Instead of going via a string, you may as well group the functions into an array:

<pre><code>function display_1() {...}

function display_2() { ... }

var functions = [ display_1, display_2 ];

function display() {
 for( var i = 0; i != functions.length; ++i ) { 
 setTimeout( functions[i], 1000 );
 }
 }
</code></pre>

If you want to go further, you may even leave out the explicit function names:

<pre><code>var functions = [
 function() { /*the function_1 implementation*/ 
 },
 function() { /*the function_2 implementation*/
 }
];
</code></pre>

blocks|key|1818850|text|您必须添加括号，以便调用该函数：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1818851|setTimeout(prefix.concat(i)%2B"()",+1000);|code-block|syntax|javascript|1818852|或者简单地说：|1818853|setTimeout(prefix+%2B+i+%2B+"()",+1000);|1818854|除此之外，请注意这两个函数是同时实际调用的，因为使用‘setTimeout()’启动的计时器同时启动。|1818855|根据您要执行的操作，您可能会查看setInterval()，或者在display_1()函数结束时启动第二个超时。|offset|length|style|CODE|1818856|entityMap^0|0|0|0|0|0|G|D|X|B|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|W|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|X|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|Y|8|@]|9|@]|A|$]]|$1|M|3|N|5|6|7|Z|8|@$O|10|P|11|Q|R]|$O|12|P|13|Q|R]]|9|@]|A|$]]|$1|S|3|-4|5|6|7|14|8|@]|9|@]|A|$]]]|T|$]]

you have to add the parenthesis so that the function is called: 

<pre><code>setTimeout(prefix.concat(i)+"()", 1000);
</code></pre>

or simply:

<pre><code>setTimeout(prefix + i + "()", 1000);
</code></pre>

Besides of that please note that both functions are called pratically at the same time, because the timers started with ´setTimeout()` start at the same time.

Depending on what you're trying to do you might have a look at <code>setInterval()</code> or start the second timeout at the end of the <code>display_1()</code> function.

It should be

<pre><code>function display_1() {

function display_2() {
alert(2);
}

function display() {
var prefix = 'display_';
for(var i = 1; i &lt; 3; i++) {
setTimeout(prefix.concat(i)+'()', 1000);
}
}

window.onload = display;

<li>the string passed to setTimeout should call the function</li>

If you really want a 1000ms delay between executing the functions, you could do something like this:

<pre><code>window.onload = function() {
 var n = 0;
 var functions = [
 function() {
 alert(1);
 setTimeout(functions[n++], 1000);
 },
 function() {
 alert(2);
 setTimeout(functions[n++], 1000);
 },
 function() {
 alert(3);
 }
 ];
 setTimeout(functions[n++], 1000);
};
</code></pre>

(rewrite it in a less-repetitive nature if needed)

I need to call the javascript function dynamically after some delay, The function display_1, 2, ... n will be dynamically constructed. My script looks like this, but the function never gets triggered if I use the following code, but if I hardcode the function it just seems to be fine.

<pre><code>function display_1() {
alert(1);
}

function display_2() {
alert(2);
}

function display() {
var prefix = 'display_';
for(var i = 1; i &lt; 3; i++) {
setTimeout(prefix.concat(i), 1000);
}

window.onload = display();
</code></pre>

我需要在一段延迟后动态调用javascript函数，函数display_1，2，...N将被动态构造。我的脚本看起来像这样，但是如果我使用下面的代码，函数永远不会被触发，但是如果我硬编码函数，它看起来就很好。function display_1() {alert(1);}function display_2() {al...
