在JavaScript代碼中與其他JavaScript代碼一起定義字體

Question

我的HTML中有這個Javascript，我想用其他Javascript代碼更改字體。

這是我使用的腳本，它按小時顯示一個句子。

<SCRIPT LANGUAGE="JavaScript"> 
day = new Date() 
hr = day.getHours() 
if (hr == 1) document.write("You can also work at night!") 
if (hr == 2) document.write("Go on! You can still push it!") 
if (hr == 3) document.write("Go go go, do not give up now!") 
if (hr == 4) document.write("Are you tired? pussy!") 
if (hr == 5) document.write("It's after 5.. just go and work some more, sleeping is almost usless now") 
if (hr == 6) document.write("Goodmorning! You made it true the night. Now GO GO GO!") 
if (hr == 7) document.write("Goedemorgen, het is 7 uur geweest.") 
if (hr == 8) document.write("Stay awake!") 
if (hr == 9) document.write("It's after 9! School starts! GO GO GO") 
if (hr == 10) document.write("Take no koffiebrake.") 
if (hr == 11) document.write("Hurry! Morning is almost finnised!") 
if (hr == 12) document.write("Damn! half of the day is alreddy gone! You are not working fast enouth!") 
if (hr == 13) document.write("No no, if you are a real good student you don't take brakes!") 
if (hr == 14) document.write("The morning is alreddy over, time is tikking!.") 
if (hr == 15) document.write("Go and get your coffie, drink it behind your computer so you wont't lose anney time!") 
if (hr == 16) document.write("No 4 o'clock for you! You still have no musch work to do!") 
if (hr == 17) document.write("What do you want to eat? Think quiq, lose no time!") 
if (hr == 18) document.write("Eat faster!") 
if (hr == 19) document.write("And back to work! To much stuff to do for tomorrow morging.") 
if (hr == 20) document.write("Take a koffie end procide") 
if (hr == 21) document.write("Eavening is almost done, have you finnised enouth work?") 
if (hr == 22) document.write("Stay strong, you can still finisch some work. Keep you focus.") 
if (hr == 23) document.write("It's nog that late yet, you dont need 9 hours sleep you pussy!") 
if (hr == 0) document.write("Come on you can still do it, finish that last parts!") 
</SCRIPT>

然后，我希望此彩虹Javascript為結果設置樣式：

<script type="text/javascript">

function toSpans(span) {
  var str=span.firstChild.data;
  var a=str.length;
  span.removeChild(span.firstChild);
  for(var i=0; i<a; i++) {
    var theSpan=document.createElement("SPAN");
    theSpan.appendChild(document.createTextNode(str.charAt(i)));
    span.appendChild(theSpan);
  }
}

function RainbowSpan(span, hue, deg, brt, spd, hspd) {
    this.deg=(deg==null?360:Math.abs(deg));
    this.hue=(hue==null?0:Math.abs(hue)%360);
    this.hspd=(hspd==null?3:Math.abs(hspd)%360);
    this.length=span.firstChild.data.length;
    this.span=span;
    this.speed=(spd==null?50:Math.abs(spd));
    this.hInc=this.deg/this.length;
    this.brt=(brt==null?255:Math.abs(brt)%256);
    this.timer=null;
    toSpans(span);
    this.moveRainbow();
}


RainbowSpan.prototype.moveRainbow = function() {
  if(this.hue>359) this.hue-=360;
  var color;
  var b=this.brt;
  var a=this.length;
  var h=this.hue;

  for(var i=0; i<a; i++) {

    if(h>359) h-=360;

    if(h<60) { color=Math.floor(((h)/60)*b); red=b;grn=color;blu=0; }
    else if(h<120) { color=Math.floor(((h-60)/60)*b); red=b-color;grn=b;blu=0; }
    else if(h<180) { color=Math.floor(((h-120)/60)*b); red=0;grn=b;blu=color; }
    else if(h<240) { color=Math.floor(((h-180)/60)*b); red=0;grn=b-color;blu=b; }
    else if(h<300) { color=Math.floor(((h-240)/60)*b); red=color;grn=0;blu=b; }
    else { color=Math.floor(((h-300)/60)*b); red=b;grn=0;blu=b-color; }

    h+=this.hInc;

    this.span.childNodes[i].style.color="rgb("+red+", "+grn+", "+blu+")";
  }
  this.hue+=this.hspd;
}

</script>



<script type="text/javascript">

var r1=document.getElementById("r1"); //get span to apply rainbow
var myRainbowSpan=new RainbowSpan(r1, 55, 0, 255, 50, 200); //apply static rainbow effect
myRainbowSpan.timer=window.setInterval("myRainbowSpan.moveRainbow()", myRainbowSpan.speed);

</script>

我不知道如何組合這些腳本。 誰能幫忙？

Answer 1

一種方法是重構原始代碼，然后簡單地調用更改

這段代碼將在您網頁上的targetElement中創建一些數據的預期范圍，然后將結果傳遞給RainbowSpan構造函數

function setTextBasedOnHour( target ) {
  var el = document.getElementById( target );
  var span = document.createElement('span');
  span.data = getTextBasedOnHour (getHour());
  el.appendChild(span);
  return el;
}

像這樣

new RainbowSpan(setTextBasedOnHour( "textBasedOnHour" ));

我添加了一個小片段來說明如何實現

 function setTextBasedOnHour( target ) { var el = document.getElementById( target ); var span = document.createElement('span'); span.data = getTextBasedOnHour (getHour()); el.appendChild(span); return el; } function getHour() { return (new Date()).getHours(); } function getTextBasedOnHour( hour ) { var texts = [ "Come on you can still do it, finish that last parts!", "You can also work at night!", "Go on! You can still push it!", "Go go go, do not give up now!", "Are you tired? pussy!", "It's after 5.. just go and work some more, sleeping is almost usless now", "Goodmorning! You made it true the night. Now GO GO GO!", "Goedemorgen, het is 7 uur geweest.", "Stay awake!", "It's after 9! School starts! GO GO GO", "Take no koffiebrake.", "Hurry! Morning is almost finnised!", "Damn! half of the day is alreddy gone! You are not working fast enouth!", "No no, if you are a real good student you don't take brakes!", "The morning is alreddy over, time is tikking!.", "Go and get your coffie, drink it behind your computer so you wont't lose anney time!", "No 4 o'clock for you! You still have no musch work to do!", "What do you want to eat? Think quiq, lose no time!", "Eat faster!", "And back to work! To much stuff to do for tomorrow morging.", "Take a koffie end procide", "Eavening is almost done, have you finnised enouth work?", "Stay strong, you can still finisch some work. Keep you focus.", "It's nog that late yet, you dont need 9 hours sleep you pussy!" ]; return texts[hour || 0]; } function toSpans(span) { var str=span.firstChild.data; var a=str.length; span.removeChild(span.firstChild); for(var i=0; i<a; i++) { var theSpan=document.createElement("SPAN"); theSpan.appendChild(document.createTextNode(str.charAt(i))); span.appendChild(theSpan); } } function RainbowSpan(span, hue, deg, brt, spd, hspd) { this.deg=(deg==null?360:Math.abs(deg)); this.hue=(hue==null?0:Math.abs(hue)%360); this.hspd=(hspd==null?3:Math.abs(hspd)%360); this.length=span.firstChild.data.length; this.span=span; this.speed=(spd==null?50:Math.abs(spd)); this.hInc=this.deg/this.length; this.brt=(brt==null?255:Math.abs(brt)%256); this.timer=null; toSpans(span); this.moveRainbow(); } RainbowSpan.prototype.moveRainbow = function() { if(this.hue>359) this.hue-=360; var color; var b=this.brt; var a=this.length; var h=this.hue; for(var i=0; i<a; i++) { if(h>359) h-=360; if(h<60) { color=Math.floor(((h)/60)*b); red=b;grn=color;blu=0; } else if(h<120) { color=Math.floor(((h-60)/60)*b); red=b-color;grn=b;blu=0; } else if(h<180) { color=Math.floor(((h-120)/60)*b); red=0;grn=b;blu=color; } else if(h<240) { color=Math.floor(((h-180)/60)*b); red=0;grn=b-color;blu=b; } else if(h<300) { color=Math.floor(((h-240)/60)*b); red=color;grn=0;blu=b; } else { color=Math.floor(((h-300)/60)*b); red=b;grn=0;blu=b-color; } h+=this.hInc; this.span.childNodes[i].style.color="rgb("+red+", "+grn+", "+blu+")"; } this.hue+=this.hspd; } new RainbowSpan(setTextBasedOnHour( "textBasedOnHour" )); 

 <div id="textBasedOnHour"></div>
