我对TextBox有疑问。当我输入重复数据时,它不允许。这正是我需要的,但在再次保存数据后,它允许重复数据。我该如何处理这个场景?

这是我的代码。

var Controls = {
    saveObjectives: function (actionurl) {
        var frm = $('form[name=frmObjectives]')
        frm.attr('action', actionurl);
        frm.submit();
    },
    addObjectiveCheckbox: function () {
        var text = $('#txtObjective').val();
        $('#txtObjective').val('');
        if ($.trim(text) == '')
            return;
        if ($('input[type=checkbox][value="' + text + '"]').length == 0)
        $('#dvObjectives').prepend('<input type="checkbox" name="chkNewobjectives" value="' + text + '" Checked /> ' + text + '<br />');
    },

我的HTML代码是:

<input id="btnAddObj" class="btn" type="button" onclick="Controls.addObjectiveCheckbox();" value="Add Objective"/>
      </div> 
    <div id="dvObjectives" name="ObjectivesList">

    @foreach (Andromeda.Core.Entities.Objectives objective in Model)
    {
        <label class="checkbox">
        <input type="checkbox" name="chkobjectives" Checked value="@objective.ObjectiveID" />@objective.ObjectiveText
        </label>
    }
</div>

你在jQuery中使用value ='what text`,但在视图中使用value ='ObjectiveID'。这应该解决它:

<input type="checkbox" name="chkobjectives" Checked value="@objective.ObjectiveText" />@objective.ObjectiveText
