将 href 值复制到文本框 onclick

Question

我正在尝试将 link onClick 的值（显示的名称）复制到文本框。可能吗？

以下是我草率的尝试使其工作 -

<div class="service_list">
    <ul style="list-style-type:square; display:none;" id="ullist">
        <li><a href="#" class="service1">Service 1</a>

        </li>
        <li><a href="#" class="service2">Service 2</a>

        </li>
    </ul>
</div>
<input type="text" id="textbox" />
<br />
<table>
    <tr>
        <td>
            <div class="button">    <a href="#" download="servicename.txt" class="button" id="button">Download</a>

            </div>
        </td>
        <td>
            <div class="list">  <a href="#" class="list" id="list">List of Services</a>

            </div>
        </td>
    </tr>
</table>

这是 JS -

var link_selected = document.querySelector('.service_list'); //edited
var input_field = document.getElementById("input");
link_selected.onclick = function (e) {
    var selected = document.querySelector('.service_list').value; //edited
    input_field.value = selected;
};

这是相同的 JSFiddle： https://jsfiddle.net/aishwarya26/rebpb5h2/

您可以为 #ullist 元素中的每个 link 添加点击处理程序，然后设置文本框的值

var text = document.getElementById('textbox');
var anchor = document.querySelector('#button');

var links = document.querySelectorAll('#ullist a');
for(var  i = 0;i< links.length;i++){
    links[i].onclick = function(){
        text.value = this.textContent || this.innerText
    }
}

使用jQuery

jQuery(function($){
    var $text = $('#textbox');
    $('#ullist a').click(function () {
        $text.val($(this).text());
    });

    $('#button').click(function (e) {
        var textbox_text = $text.val();
        var textbox_file = new Blob([textbox_text], {
            "type": "application/bat"
        });

        this.href = URL.createObjectURL(textbox_file);
        this.download = "servicename.txt";
    });

    $('#list').click(function (e) {
        $('#ullist').toggle();
    });
})

像这样在页面加载时使用点击触发器，如果您愿意尝试一下 jquery:

    $('a').click(function(){
        $('#textbox').val($(this).html());
    })

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="service_list">
    <ul style="list-style-type:square; display:none;" id="ullist">
        <li><a href="#" class="service1">Service 1</a>

        </li>
        <li><a href="#" class="service2">Service 2</a>

        </li>
    </ul>
</div>
<input type="text" id="textbox" />
<br />
<table>
    <tr>
        <td>
            <div class="button">    <a href="#" download="servicename.txt" class="button" id="button">Download</a>

            </div>
        </td>
        <td>
            <div class="list">  <a href="#" class="list" id="list">List of Services</a>

            </div>
        </td>
    </tr>
</table>

由于 JQuery 被标记，这可以简单地用 JQuery!

完成

$(document).on('click', 'a', function(e) {
    e.preventDefault();
    //e = $(this).attr('href');//this gets the href
    e = $(this).text();//This gets the text
    $('input').val(e);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input readonly>
<a href="http://google.com">Google<a>
<a href="http://booble.com">Booble<a>

你也可以使用 live jquery click for this
