我正在制作公司技术支持联系人的通讯簿,管理员可以以表格的形式访问所有地址。在此表中,他可以添加,删除和更改同一页面中的数据。
我已经成功设置了add
和delete
函数,但是我在edit
方面做了大量工作。我正在使用node,express,mongodb和vanilla javascript。
我仍然是Web开发领域的新手,有些话我可能会用错,所以请提前对不起!
(对不起,我的法语,但是大多数单词在英语中的含义相同。)
我的HTML
<div>
<input id="edit" type="button" value="Editer" onclick="return edit()">
<input id="valider" type="hidden" value="Valider" onclick="return valider()">
</div>
<table id='myTable'>
<thead>
<tr class="header">
<th>Nom de l'entreprise</th>
<th>Téléphone 1</th>
<th>Téléphone 2</th>
<th>Mail</th>
</tr>
</thead>
<tbody>
<% companies.forEach(function(company){ %> //I loop through my db
<tr class="compName">
<td hidden id='_id' > <%= company._id %> </td>
<td> <input id="name" class="readonly" type="text" value=" <%= company.name %>" readonly style="border: none" onblur="change(this)"> </td>
<td> <input id="phone" class="readonly" type="text" value=" <%= company.phone %>" readonly style="border: none" onblur="change(this)"> </td>
<td> <input id="phone2" class="readonly" type="text" value=" <%= company.phone2 %>" readonly style="border: none" onblur="change(this)"> </td>
<td> <input id="mail" class="readonly" type="text" value=" <%= company.mail %>" readonly style="border: none" onblur="change(this)"> </td>
</tr>
<% }) %>
</tbody>
</table>
我的脚本
<script>
function edit() {
var editComp = document.getElementsByClassName("readonly");
var edit = document.getElementById('edit').type = 'hidden'; //get the edit button and hide it
var valider = document.getElementById('valider').type = 'button'; //then unhide the validate button so I can use it
for (var i = 0; i < editComp.length; i++) { //remove the readonly for each td so I can edit it
editComp[i].removeAttribute('readonly');
editComp[i].setAttribute("style", "border: 1px solid red;");
};
}
function valider() {
var editComp = document.getElementsByClassName("readonly");
var edit = document.getElementById('edit').type = 'button'; //unhide the edit button
var valider = document.getElementById('valider').type = 'hidden' //hide my validate button
for (var i = 0; i < editComp.length; i++) { //put back the readonly for each td so its uneditable
editComp[i].setAttribute('readonly', true);
editComp[i].setAttribute("style", "border: none;");
};
}
function change(element) { //when the input gets unfocused, I assume that's because changes happened
var setChanged = element.setAttribute("class", "readonly changed"); //I mark all changed element
/*I want to udapte my database with the changed elements
I was thing of getting the hidden company._id and the id of the changed element so I can update them specifically*/
}
</script>
因此,我想到了要获取更改后的行的col [0],它是更改后的元素的_id,因此我可以将其定位为在数据库中进行更新,但是我不知道该怎么做
谢谢!
