Jquery val（）不会带回文本框的值

Question

我正在尝试在我的对象中分配文本框值，但根本没有得到任何值。我的文本框保存在一个模态中，当我单击提交按钮时，该命令会触发，该按钮代码确实点击了作业，但它没有取回键入的值。

if (($("#editWidgetModal").data('bs.modal') || {}).isShown) {
        //check for onclick event for the save button
        $('#edit-widget').on('click', null, function (event) {
            event.preventDefault()
            var completed;

            //loop through each input box in the modal
            $('#editWidgetModal input[type=text]').each(function () {
                if (this.value == "") {
                    alert("Please enter all fields");
                    completed = false;
                    return false;
                } else {
                    completed = true;
                    return false;
                }
            });

            if (completed) {

                //Now assign all textboxes and create an object to pass into the lineBasedChart mutator
                var chartEditOptions = {
                    title: $('#chart-title').val(),
                    subtitle: $('#chart-subtitle').val(),
                    yAxis: $('#chart-yAxis').val(),
                    tooltip: $('#chart-tooltip').val(),
                    lineWidth: parsetInt($('#chart-lineWidth').val())
                };

                //set renderTo data attribute to the widgets created element
                overlayedData.data("data-render", overlayedData.closest('.grid-stack-item-content').attr('id'));
                chart[0].SetNewOptions(chartEditOptions);
                $('#editWidgetModal').modal('hide');
            }

        });
    }

这是我的HTML

Answer 1

运行脚本时，文本框不在DOM中。

Answer 2

您的代码中有拼写错误：parsetInt应为parseInt ...

你检查过你的控制台吗？

$('#edit-widget').on('click', null, function (event) {
  event.preventDefault()
  handleFormData();
})

  function handleFormData() {
    var chartEditOptions = {
      title: $('#chart-title').val(),
      subtitle: $('#chart-subtitle').val(),
      yAxis: $('#chart-yAxis').val(),
      tooltip: $('#chart-tooltip').val(),
      lineWidth: parseInt($('#chart-lineWidth').val())
    };

    
    document.getElementById('result').innerHTML = JSON.stringify(chartEditOptions);
    
  }
