jTable根据数据所有者有条件地显示\隐藏编辑和删除按钮 [英] jTable Conditional show\hide edit and delete buttons based on owner of data
问题描述
我使用jTable显示CD信息，并使用子表显示该CD的评论.我希望只能在登录用户的行上显示"edit \ delete"按钮.我一直在尝试遵循以下建议:
Im using jTable to display CDs info and a child table to show reviews of that CD. I want to be able to only show the edit\delete buttons on the rows for the user that is logged in. I have been trying to follow the suggestions made on: https://github.com/hikalkan/jtable/issues/113
https://github.com/hikalkan/jtable/issues/893
https://github.com/hikalkan/jtable/issues/620
可以诚实地说，我对这些示例都不太满意.我们被告知要在我们的分配中包含一些jquery，因此我选择将其用于表数据.我希望现在的ID可以做一些非常基本的事情！
Can honestly say im not having much luck with any of these examples. We had been told to include some jquery in our assignment so I chose to go with using it for my table data. Im wishing now id just done something very basic!
在没有条件的情况下运行jTable:
Working jTable without condition:
display: function (reviewData) {
//Create an image that will be used to open child table
var $img = $('<img class="child-opener-image" src="/Content/images/Misc/list_metro.png" title="List Reviews" />');
//Open child table when user clicks the image
$img.click(function () {
$('#ReviewTableContainer').jtable('openChildTable',
$img.closest('tr'),
{
title: "Your reviews on this album",
actions: {
listAction: 'childReviewActions.php?action=list&ID=' + reviewData.record.CDID,
deleteAction: 'childReviewActions.php?action=delete&ID=' + reviewData.record.CDID,
updateAction: 'childReviewActions.php?action=update&ID=' + reviewData.record.CDID
},
fields: {
userID: {
key: true,
create: false,
edit: false,
list: false
},
userName: {
title: 'User',
edit: false,
width: '20%'
},
reviewDate: {
title: 'Review date',
width: '20%',
type: 'date',
edit: false,
displayFormat: 'dd-mm-yy'
},
reviewText: {
title: 'Review',
type: 'textarea',
width: '40%'
}
},
问题620尝试:
actions: {
listAction: 'childReviewActions.php?action=list&ID=' + reviewData.record.CDID,
@if (reviewData.record.userID == <?php echo mysql_real_escape_string($_SESSION['ID']);?>)
{
deleteAction: 'childReviewActions.php?action=delete&ID=' + reviewData.record.CDID,
updateAction: 'childReviewActions.php?action=update&ID=' + reviewData.record.CDID
}
},
这种方式给我编译错误:IF语句上的无效属性ID. 如果我在if语句中删除@，则会得到:属性ID后缺少:.
This way gives me compile error: invalid property id on the IF statement. If I take out the @ in the if statement I get: missing : after property id.
问题113和893次尝试:
Issue 113 & 893 attempt:
actions: {
listAction: {
url:'http://localhost/childReviewActions.php?action=list&ID=' + reviewData.record.CDID
//updateAction: {
//url:'childReviewActions.php?action=update&ID=' + reviewData.record.CDID,
//enabled: function (data) {
//return data.record.userID = <?php echo mysql_real_escape_string($_SESSION['ID']);?>;
//}
//}
},
在这一点上，我什至无法列出子表的内容.它不断返回404 not found错误:在此服务器上找不到请求的url/[object object].有谁知道如何使这些示例正常工作吗，还有其他示例如何使表格启用\启用编辑，更新按钮吗?这对我来说是新事物，所以我向您道歉
On this I couldnt even get it to list the contents of the child table. It keeps coming back with 404 not found error: The requested url /[object object] was not found on this server. Has anyone any ideas how to get these examples working on have a different example of how to get the table to enable\enable the edit, update buttons? This is all new to me so I apologise now
推荐答案
rowInserted: function (event, data) {
//After child row loads. Check if the review belongs to the member logged in. If not remove the edit/delete buttons
if (data.record.userID != $user) {
data.row.find('.jtable-edit-command-button').hide();
data.row.find('.jtable-delete-command-button').hide();
}
else{
//If a review record does belong to the user set variable to true so the add new review link can be hidden after all records have been loaded
$memberReviewExists = true;
//Also needed here for when a new record is inserted
$(".jtable-add-record").hide();
}
},
recordsLoaded: function (event, data) {
if (typeof $memberReviewExists != 'undefined' && $memberReviewExists == true){
$(".jtable-add-record").hide();
$memberReviewExists = null;
}
else {
//No review currently exists for this user so show the Add review link $(".jtable-add-record").show();
}
},
recordDeleted: function (event, data) {
//User has deleted their review. Re-show the add new review link
$(".jtable-add-record").show();
}
