标签文本更改时触发输入单击事件

Question

1. 我有一个id为lblResult的标签
2. 我有以下代码： @（Html.TreeView（Model）.EmptyContent（“root”）。Kidren（m => m.Childs）.HtmlAttributes（new {id =“tree”}）。KidrenHtmlAttributes（new {@class =“subItem”}） .ItemText（m => m.AssetNumber）.ItemTemplate（@@ * @ item.AssetNumber * @））
3. 然后，我在视图上有以下代码：

@using (Html.BeginForm("AssetTypeIndex", "ControlFiles", FormMethod.Get)) { <div class="row"> <div class="col-lg-offset-2 col-lg-8 col-lg-offset-2"> <div class="form-inline"> <div class="input-group"> <span class="input-group-addon" id="basic-addon1">Search</span> @Html.TextBox("SearchString", ViewBag.CurrentFilter as string, new { @class = "form-control" }) <span class="input-group-btn"> <button class="btn btn-default" type="submit" value="Search">View</button> </span> </div> <div class="pull-right"> <a [email protected]("AssetTypeCreate", "ControlFiles") class="btn btn-default">Create New</a> </div> </div> </div> </div> }

4. 在脚本部分： $（function（）{var selectedData; $（'＃jstree'）。jstree（{“core”：{“multiple”：true，“check_callback”：true，'themes'：{“responsive”：true，'variant '：'small'，'stripes'：false，'dots'：true}}，“types”：{“default”：{“icon”：“glyphicon glyphicon-record”}，“root”：{“icon” ：“glyphicon glyphicon-ok”}}，“plugins”：[“dnd”，“state”，“types”，“sort”]}）。on（'changed.jstree'，function（e，data）{var i，j，r = []; for（i = 0，j = data.selected.length; i

如果你看到上面的代码。有一个提交按钮，触发控制器上的搜索功能。 我的问题是，是否可以在不点击按钮的情况下运行“搜索功能”？当lblResult从jsTree收到文本时，我想运行'搜索功能'，这意味着当lblResult文本发生变化时。

请指教。 谢谢。

Option 1: When clicking a node on your jsTree trigger that submit function by simulating a mouse-click using click method. As you know for sure the label will be changing.

@using (Html.BeginForm("AssetTypeIndex", "ControlFiles", FormMethod.Get)){
    <div class="row">
        <div class="col-lg-offset-2 col-lg-8 col-lg-offset-2" style="margin-top:-5px;">
            <div class="form-inline">
                <div class="input-group">
                    <span class="input-group-addon" id="basic-addon1">Search</span>
                    @Html.TextBox("SearchString", ViewBag.CurrentFilter as string, new { @class = "form-control" })
                    <span class="input-group-btn">
                        <button class="btn btn-default" id="submitSearch" type="submit" value="Search">View</button>
                    </span>
                </div>

                <div class="pull-right">
                    <a [email protected]("AssetTypeCreate", "ControlFiles") class="btn btn-default">Create New</a>
                </div>
            </div>
        </div>
    </div>
}
$("#submitSearch").click(); // use the code when clicking a node on jsTree

Option 2: If you are manually changing the label by entering in a textbox then use the keyup event to trigger submit function.

$(function(){
  $("#lblreasult").on('keyup', function(){
    $("#submitSearch").click();
  });
});

很抱歉我迟到的回复，当你点击jsTree ex中的节点时：标签的id是node1，你可以删除这段代码

<span class="input-group-btn">
     <button class="btn btn-default" id="submitSearch" type="submit" value="Search">View</button>
 </span>

或者添加这个css代码

#submitSearch{display:hidden}

我在你的代码中编辑了一下

$('#jstree').on('changed', function (e, data) { 
    var i, j = data.selected.length, r = []; 
    for(i = 0,  i < j; i++) { 
        r.push(data.instance.get_node(data.selected[i]).text); 
    } 
    $('#event_result').html('Selected: ' + r.join(', ')); 
    $('#lblResult').text('your text here');//
    $('form').submit();
});
