我有一个具有contenteditable值的表,当我更改值时,ajax动作将更新DB的值。
问题是在警报继续出现后,单击框然后单击另一个框,然后又不能执行其他任何操作。
有没有一种方法可以防止其他点击功能一旦启动?

代码JS:

function showEdit(editableObj) {
  $(editableObj).css("background", "#FFF");
}

function saveToDatabase(editableObj, column, id) {
  var isGood = confirm('Are you sure?');
  if (isGood) {

    $(editableObj).css("background", "#FFF url(./img/loaderIcon.gif) no-repeat right");
    $.ajax({
      url: "saveedit.php",
      type: "POST",
      data: 'column=' + column + '&editval=' + editableObj.innerHTML + '&id=' + id,
      success: function(data) {
        $(editableObj).css("background", "#FDFDFD");
      }
    });
    //  }
  } else {
    alert('Abort');
  }
}


php表:

echo '<td contenteditable="true" onBlur="saveToDatabase(this, \'nameDB\', \''.$res2['valuefromDB'].'\')" onClick="showEdit(this);">' .$res2['valuefromDB'] .'</td>';

最佳答案

您可以使用标志来阻止激活:

var saveEnabled = true; // Only let you save when this is true
function saveToDatabase(editableObj, column, id) {
  if (!saveEnabled) return; // If saveEnabled is false do not continue
  saveEnabled = false;
  var isGood = confirm('Are you sure?');
  if (isGood) {
    $(editableObj).css("background", "#FFF url(./img/loaderIcon.gif) no-repeat right");
    $.ajax({
      url: "saveedit.php",
      type: "POST",
      data: 'column=' + column + '&editval=' + editableObj.innerHTML + '&id=' + id,
      complete: function(data) { // Errors should be handled before this
        $(editableObj).css("background", "#FDFDFD");
        saveEnabled = true;
      }
    });
    //  }
  } else {
    alert('Abort');
    saveEnabled = true;
  }
}
