Question

我的代码无效，我需要从列表中找到最小值，我必须使用，但由于某种原因它并不总是有效

<script>

  /* Example one */
  function findMin()
 {

    list = numbersBox.value.split(",");      // gets the input into an array form by splitting on ","
    var min = list[0];                       // assuming initially that min element is the first element

    for(var i = 0; i < list.length; i++)     // for loop to go over all list elements starting from 0 to list.length
    {
         if(list[i] < min) min = list[i];                  // setting the min value appropriately
    }

    minBox.value = min;                     // setting answer into the minBox

}

</script>

<label>Write some numbers separated by commas:</label>
<br><br>
<input type="text" id="numbersBox" />
<br><br>
<label>Minimum Value:</label>
<br><br>
<input type="text" id="minBox" />
<br><br>

找到最小

Answer 1

您可以使用Math.min()：

<label>Write some numbers separated by commas:</label>
<br><br>
<input type="text" id="numbersBox" value="9,6,12,67"/>
<br><br>
<label>Minimum Value:</label>
<br><br>
<input type="text" id="minBox" />
<br><br>
<button onclick="findMin()">Find min</button>

public class makeMyTrip {
public static void main(String[] args) {
System.setProperty("webdriver.gecko.driver", "C:\\jarFiles\\geckodriver-v0.14.0-win64\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.get("https://www.makemytrip.com/");

driver.findElement(By.cssSelector("a[href*='holidays-international']")).click();
String MainWindow=driver.getWindowHandle();

for(String winHandle : driver.getWindowHandles()){
driver.switchTo().window(winHandle);
}

driver.close();
// Switching to Parent window i.e Main Window.
driver.switchTo().window(MainWindow);

//driver.findElement(By.xpath("//[@placeholder='Type Departure City']")).sendKeys("New Delhi");
}
}

Answer 2

尝试以下方法：

＆＃13;

function findMin()
 {

    list = $('#numbersBox').val().split(",");      // gets the input into an array form by splitting on ","
    var min = list[0];                       // assuming initially that min element is the first element
    Array.min = function( array ){
        return Math.min.apply( Math, array );
    };
    $('#minBox').val(Array.min(list));

}
$('#btnClick').click(function(){ 
    findMin();
})

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<label>Write some numbers separated by commas:</label>
<br><br>
<input type="text" id="numbersBox" />
<br><br>
<label>Minimum Value:</label>
<br><br>
<input type="text" id="minBox" />
<input type="button" value="Result" id="btnClick"/>
<br><br>

我的最小值按钮不起作用，HTML和Javascript
