比较复选框和输入值

时间：2015-09-25 16:38:31

标签： jquery checkbox icheck

问题：

我试图将复选框值与同一表格行中的输入值进行比较。我在关键字上比较它们。当用户填写文本框中的值时，它会将该值与复选框的值进行比较。如果值相等，我希望复选框进入选中状态。

有趣的是，我的代码执行了此操作，但仅限于复选框/输入的第一个实例。请注意，我使用的是icheck插件，因此我使用了一些自定义事件。我们赞赏任何正确方向的帮助。

请参阅下面的代码段。

＆＃13;
＆＃13; 
$(function() {
  var payFull = $('input[type="checkbox"].payfull');
  var payNow = $('input[type="text"].paynow');
  var payAmt = $('#amounttopay');

  // Recalc Function
  function reCalc() {
      var sum = 0;
      payNow.each(function() {
        sum += Number($(this).val());
      });
      if (!isNaN(sum) && sum.length !== 0) {
        payAmt.html('$' + sum.toFixed(2));
      } else {
        payAmt.html('$0.00');
      }
    }
    // When Pay in Full Checkbox is Checked fill in Pay This Time Field with Invoice Amount Due Value
  payFull.on('ifChecked', function(event) {
    var val = $(this).val().replace('$', '');
    var price = $(this).closest('tr').find('input[type="text"]').val(val);
    price;
    reCalc;
  });

  // If Pay in Full Unchecked then remove value from respective Pay This Time Input
  //if (event.target.checked === true) { // Only bind the ifUnchecked event if the checkbox is checked
    payFull.on('ifUnchecked', function(event) {
      var removePrice = $(this).closest('tr').find(payNow).val('');
      $(removePrice);
      $(reCalc);
    });
  //}

  // If Pay This Time changes recalculate total
  var payFullVal = payFull.val().replace('$', '');
  payNow.keyup(function(event) {
    //  If Checkbox and Input values DO NOT match
    if (payFullVal !== $(this).val()) {
      $(this).closest('tr').find(payFull).iCheck('uncheck');
    }
    //  If Checkbox and Input values DO match
    else if (payFullVal == $(this).val()) {
      $(this).closest('tr').find(payFull).iCheck('check');
    } else {}
    $(reCalc);
  });
});
