如何获取选中复选框的值和该复选框的输入文本值？

Question

我有一个复选框列表以及每个复选框的输入文本。如果未选中该复选框，我将禁用可以正常工作的输入文本。我想获取选中的复选框的值以及用户为该特定复选框提供的输入。我可以获取选中复选框的值问题是获取输入文本的值。

例如：

1. CHECKBOX - 如果未选中，则禁用输入文本

2. INPUTTEXT - 如果选中复选框，用户就可以输入数据。

我怎样才能做到这一点。您的帮助在高级表示赞赏

这样使用

// Returns an array with values of the selected (checked) checkboxes in "frm"
function getSelectedChbox(frm) {
  var selchbox = [];        // array that will store the value of selected checkboxes

  // gets all the input tags in frm, and their number
  var inpfields = frm.getElementsByTagName('input');
  var nr_inpfields = inpfields.length;

  // traverse the inpfields elements, and adds the value of selected (checked) checkbox in selchbox
  for(var i=0; i<nr_inpfields; i++) {
    if(inpfields[i].type == 'checkbox' && inpfields[i].checked == true) {
    console.log(inpfields[i].id);
    var textboxVal = document.getElementById(inpfields[i].id+"code").value;
console.log(textboxVal);
    var obj = {checkbox:inpfields[i].value,textbox:textboxVal};
    	selchbox.push(obj);
    }			
  }
  return selchbox;
}
  /* Test this function */
// When click on #langtest, alert the selected values
document.getElementById('langtest').onclick = function(){
  var selchb = getSelectedChbox(this.form);     // gets the array returned by getSelectedChbox()
  alert(JSON.stringify(selchb));
}



//Check if checkbox is checked, if not checked disable input text
 document.getElementById('html').onchange = function() {
    document.getElementById('htmlcode').disabled = !this.checked;
  };
  document.getElementById('css').onchange = function() {
    document.getElementById('csscode').disabled = !this.checked;
  };
  document.getElementById('javascript').onchange = function() {
    document.getElementById('javascriptcode').disabled = !this.checked;
  };
  document.getElementById('php').onchange = function() {
    document.getElementById('phpcode').disabled = !this.checked;
  };
  document.getElementById('python').onchange = function() {
    document.getElementById('pythoncode').disabled = !this.checked;
  };
  document.getElementById('net').onchange = function() {
    document.getElementById('netcode').disabled = !this.checked;
  };
  document.getElementById('mysql').onchange = function() {
    document.getElementById('mysqlcode').disabled = !this.checked;
  };
