HTML page, test JS call to C function

不言Original: 2018-06-05 15:36:281852browse

The following is an HTML page for you to test a simple example of JS calling C functions. It’s pretty good. I’ll share it with you now and give it as a reference. Come and take a look together

Note it here so you can check it when you need to use it later!

    var arg2 = document.getElementById("func2_input2").value;
    alert(window.myKagulaFunc2(arg1,arg2));
    //正确返回"head and tail"字符串。
  }
  function testCallFunc3()
  {
    var oldValue = window.myKagulaVal;
    var arg = document.getElementById("func3_input").value;
    window.myKagulaFunc3(arg);
