我在函数中有一个input type='number'
和一个按钮,用于指示function testfun()
和一个if语句,该语句用来验证数字是否在范围内并提供清晰的指令。
当我输入1-1000范围内的数字时,它可以正常工作。
当我输入小于1或> 1000的数字时,<div><p>
不会填充。
HTML:
<div class="preT" id="preT">
<form>
<label for="voipLines">VoIP Lines</label>
<input type="number" id="voipLines" name="voipLines" requiered min="1" max="1000" value="1">
</form>
<div class="voipbutton" id="voipbutton">
<button class="button" onclick="testfun()">Test Clicker</button>
</div>
</div>
<div id="duringT">
<p Id="clickerTest"></p>
<div Id="prBar" data-label=""></div>
<div id="canvascon"></div>
</div>
JS:
function testfun() { //used in HTML
var voip = document.getElementById("voipLines").value;
if (voip < 1) { //voiplines verification
return document.getElementById("clickerTest").innerHTML = "<div><p>Make Sure VoIP Lines is within the range of 1 to 1000</p></div>";
} else if (voip > 1000) {
return document.getElementById("clickerTest").innerHTML = "<div><p>Make Sure VoIP Lines is within the range of 1 to 1000</p></div>";
} else {
var voipGuide = document.getElementById("clickerTest").innerHTML = '<h2>Clicker Successful!!!</h2>\
<p>Please click the link below to start <b>' + voip + ' test</b></p>\
<p>To change the amount of tests to run <a href= "">Click Here</a></p>';
document.getElementById('preT').style.display = 'none';
document.getElementById("canvascon").innerHTML = '<div id="canvas-container"><canvas id="canvs3" style="background-color:#F0F0F0; ">Your browser does not support the HTML5 canvas tag.</canvas><br><br></div>';
voipsims();
bootfun();
}
}

在else正文中,您使用innerHTML,但在if和else中,您使用innerhtml。应该是innerHTML

这是Codepen中的工作版本。 https://codepen.io/riza-khan/pen/YzwwRLQ?editors=1011
您的代码中存在一些不良做法。也就是说,最好先使用eventListeners,然后再通过HTML标签中的onclick调用函数。
第二,在拼写错误中有一些拼写错误。
通过更正,甚至不需要IF / ELSEIF块,但是我还是把它留在那里。
<div class="preT" id="preT">

有一个拼写错误:该属性为.innerHTML
,而不是.innerhtml
。工作示例:
function testfun() { //used in HTML
var voip = document.getElementById("voipLines").value,
clickerTest = document.getElementById("clickerTest");
if (voip < 1) //voiplines verification
return clickerTest.innerHTML = "<div><p>Make Sure VoIP Lines is within the range of 1 to 1000</p></div>";
else if (voip > 1000)
return clickerTest.innerHTML = "<div><p>Make Sure VoIP Lines is within the range of 1 to 1000</p></div>";
else {
var voipGuide = clickerTest.innerHTML = '<h2>Clicker Successful!!!</h2>\
<p>Please click the link below to start <b>' + voip + ' test</b></p>\
<p>To change the amount of tests to run <a href= '
'>Click Here</a></p>';
document.getElementById('preT').style.display = 'none';
document.getElementById("canvascon").innerHTML = '<div id="canvas-container"><canvas id="canvs3" style="background-color:#F0F0F0; ">Your browser does not support the HTML5 canvas tag.</canvas><br><br></div>';
}
}
<div class="preT" id="preT">
<form>
<label for="voipLines">VoIP Lines</label>
<input type="number" id="voipLines" name="voipLines" min="1" max="1000" value="1" required>
</form>
<div class="voipbutton" id="voipbutton">
<button class="button" onclick="testfun()">Test Clicker</button>
</div>
</div>
<div id="duringT">
<p id="clickerTest"></p>
<div id="prBar" data-label=""></div>
<div id="canvascon"></div>
</div>

我不确定这个答案,但是我认为innerhtml应该是innerHTML,并且'if','else if','else'和“ {”和“}”之间不应有空格。所以应该是 “
如果(voip <1){
...
}否则,如果(voip> 1000){
...
}其他{
...
} “
在段落末尾也有一个\,请单击链接...我认为这是不正确的。
