Question

具有一个带有两个子按钮的主按钮。如果选中子按钮后面的复选框，则子按钮从红色变为绿色。如果两个子按钮均为绿色，则主按钮应从红色变为绿色

试图创建一个脚本来做到这一点。如果我运行不带“ ChangeGCPOD”功能的代码，则如果选中此复选框，则子按钮会更改颜色。但是使用功能“ ChangeGCPOD”，子按钮不会更改颜色，主按钮也不会更改颜色

 //  If checkbox is checked equipment is NOT in run, then background row    equipment change to grey and Color button from red to green-->
    function ChangeRowColor(chkrow, row, cel, btn) {
      var varrow = document.getElementById(row);
      var varcel = document.getElementById(cel);
      var varColor = "#E3CEF6";
      var varColor2 = "Yellow";
      if (chkrow.checked == true) {
        varColor = "Grey";
        varColor2 = "Grey";
        document.getElementById(btn).style.backgroundColor = 'green';
      } else {
        document.getElementById(btn).style.backgroundColor = 'red';
      }
      varrow.style.backgroundColor = varColor;
      varcel.style.backgroundColor = varColor2;
      ChangeGCPOD();
    }

    function ChangeGCPOD() {
      var varE1 = document.getElementById('b_echo_01');

      } else {

如果两个子键都为绿色，则希望更改主按钮的颜色

实际上您的逻辑是正确的，只是条件错误，您在=行中使用==而不是if (varE1.style.backgroundColor = varColor2 && varE2.style.backgroundColor = varColor2)

 function ChangeRowColor(chkrow, row, cel, btn) {
      var varrow = document.getElementById(row);
      var varcel = document.getElementById(cel);
      var varColor = "#E3CEF6";
      var varColor2 = "Yellow";
      if (chkrow.checked == true) {
        varColor = "Grey";
        varColor2 = "Grey";
        document.getElementById(btn).style.backgroundColor = 'green';
      } else {
        document.getElementById(btn).style.backgroundColor = 'red';
      }
      varrow.style.backgroundColor = varColor;
      varcel.style.backgroundColor = varColor2;
      ChangeGCPOD();
    }

    function ChangeGCPOD() {
        var varE1 = document.getElementById('b_echo_01');
        var varE2 = document.getElementById('b_echo_02');
        var varColor = "red";
        var varColor2 = "green";
        
        if (varE1.style.backgroundColor == varColor2 && varE2.style.backgroundColor == varColor2) {
            document.getElementById('gcpod').style.backgroundColor = 'green';
        } else {
            document.getElementById('gcpod').style.backgroundColor = 'red';
        
        }
      }
