For simple use, see w3school There is no parameter call in The example is as follows Copy code Code As follows: <br>function timedMsg() <br>{ <br>var a ="dd"; <br>var t= setTimeout(function(){ cao(a);},3000) <br>} <br>function cao(a) <br>{ <br>alert(a); <br>} <br></script> ; <BR></head> <br> </div> <br><input type="button" value="Display timed warning box" onClick = "timedMsg()"> <br><br> My current problem is that only the last one is sent back among multiple ones. Think about it <br><br> I still don’t understand it, I understand <br><div class="codetitle"> <span><a style="CURSOR: pointer" data="67116" class="copybut" id="copybut67116" onclick="doCopy('code67116')"><u>Copy code </u></a></span> The code is as follows: </div> <div class="codebody" id="code67116"> <br>/* for (var i=0;i<points.length;i ){ <br>AddGuiJi(points[i],value ); <br>//var t=setTimeout(function(){ AddGuiJi(points[i],value);},2000*i) <br>} */ <br> </div> <br>Error in the above The reason is that when time is triggered for execution, i=4, so although there are multiple ones, it is always the last one <br><br>Solution<br><div class="codetitle"> <span><a style="CURSOR: pointer" data="45090" class="copybut" id="copybut45090" onclick="doCopy('code45090')"><u>Copy code</u></a></span> The code is as follows: </div> <div class="codebody" id="code45090"> <br>var timerr; <br>function xunhuanlian(points,value){ <br>if(replayi<points.length){ <br>AddGuiJi (points[replayi],value); <br>replayi ; <br>timerr=setTimeout(function(){ xunhuanlian(points,value);},1000); <br>} <br>else{ <br>replayi =0; <br>clearTimeout(timerr); <br>} <br>/* for (var i=0;i<points.length;i ){ <br>AddGuiJi(points[i],value); <br>//var t=setTimeout(function(){ AddGuiJi(points[i],value);},2000*i) <br>} */ <br>} <br> </div>
