jQuery将div的高度设置为另一个的“动态高度”(jQuery set height of a div to the 'dynamic height' of another)

我有两个div。

  <div class="col-1"><p>Content</p></div>
  <div class="col-2"><img src="" alt="" /></div>

每个人都有他们尊重的内容。

我正在设置col-2的高度与col-1的高度完全一致。

我尝试使用jQuery:

   $(document).ready(function() {
        var divHeight = $('.col1').height(); 
        $('.col2').css('min-height', divHeight+'px');
    });

问题是col-1没有设置高度。 它的内容在增长时会有一个动态的高度。 因此,上面的代码不适用于它。

有没有什么办法可以将col-2的最小高度设置为与使用jQuery的col 1的动态高度相等?


I have two divs.

  <div class="col-1"><p>Content</p></div>
  <div class="col-2"><img src="" alt="" /></div>

With their respected content inside each one.

I am trying to set the height of col-2 to be exactly as that of col-1.

I tried this using jQuery:

   $(document).ready(function() {
        var divHeight = $('.col1').height(); 
        $('.col2').css('min-height', divHeight+'px');
    });

The problem is that col-1 does not have a height set on it. It has a dynamic height which grows when its content grows. Therefore the above code does not work for it.

Is there any way I can set the min height of col-2 to be equal to the dynamic height of col 1 using jQuery?

一个简单的方法是检查Integer.toHexString()输出多少个数字,如果需要,可以向每个字节添加一个前导零。 这样的事情

public static String toHexString(byte[] bytes) {
    StringBuilder hexString = new StringBuilder();

    for (int i = 0; i < bytes.length; i++) {
        String hex = Integer.toHexString(0xFF & bytes[i]);
        if (hex.length() == 1) {
            hexString.append('0');
        }
        hexString.append(hex);
    }

    return hexString.toString();
}

A simple approach would be to check how many digits are output by Integer.toHexString() and add a leading zero to each byte if needed. Something like this:

public static String toHexString(byte[] bytes) {
    StringBuilder hexString = new StringBuilder();

    for (int i = 0; i < bytes.length; i++) {
        String hex = Integer.toHexString(0xFF & bytes[i]);
        if (hex.length() == 1) {
            hexString.append('0');
        }
        hexString.append(hex);
    }

    return hexString.toString();
}
