为什么没有从表单按钮单击调用javascript方法?

为什么不从表单中的按钮调用单击事件来调用此函数。我没有看到没有理由不通过click事件调用它。一切都在全球范围内,我不确定是好还是坏。

代码:

function hex_md5(s)
{ 
    return binl2hex(core_md5(str2binl(s), 
                    s.length * chrsz));
}

    <form>
      <td>
        <font color=#00FF00 size=3>Input</font>  
      </td>
      <td > 
        <input type=text name=input1 size=60>
        </br>
      </td>
      <td>    
        <font color=#000000 size=3>Result</font> 
      </td>
      <td> 
        <input type=text name=hash size=60>
        </br>
      </td>
      <td>  
        <input type=button value="MD5 It!" onclick="hash.value = hex_md5(input1.value)">
        </br>
      </td> 
    </form>

问题:

function binl2str(bin)
{
  var str = "";
  var mask = (1 << chrsz) - 1;
  for(var i = 0; i < bin.length * 32; i += chrsz)
    str += String.fromCharCode((bin[i>>5] >>> (i % 32)) & mask);
    if (str == "") {
        return "Empty String";
    } else {
        return str;
    }
}

此代码返回空字符串或空值。

以下是整个代码。

以下代码可行。但是,你需要自己检查你的md5功能,因为我没有它

    var s = document.getElementById("input1");
    var s1 = document.getElementById("hash");

如果您尝试进行基于Rsa的加密,请尝试这样。
