这是删除链接
<div class="artworkdelete">
<a href="javascript:void(0);" id="del_<?=$artworkDetails['artwork_id'] ?>_<?=$temp_cat_id; ?>" onclick="deleteThisArtWork(this.id)">Delete</a>
</div>
显然，当点击该链接时，门户网站会自动删除数据，我认为这是一个ajax，因为页面不会刷新。所以我被要求添加一个确认弹出窗口，要求用户单击是或否，如果他想要删除数据，并在确认框中，它应该提到要删除的数据的名称，例如
"are you sure you want to delete row_title ?"
这是deleteThisArtWork（）
的功能 function deleteThisArtWork(artwork_id){
var artwork_id = artwork_id.split('_');
var cat_id=artwork_id[2];
artwork_id = artwork_id[1];
//$('#divStatus').html('processing request, please wait');
//$(".pleaseWait").dialog("open");
openLightBox();
$.ajax({
type: 'POST',
url: '<?php echo BASE_URL;?>ajax/ajax_methods_gallery.php',
data: 'deleteartwork=yes&artwork_id='+artwork_id+'&category_id='+cat_id,
success: function(msg){
//alert(msg);
msg = 'done';
var status=msg;
var deleted='';
if(status == 'done') {
var temp_lid = 'li_'+artwork_id+'_'+cat_id+'_';
//alert(counter);
for(var v=1;v<counter;v++){
var curid = tempIdArr[v];
curid = curid.split('#');
var curlid = curid[0];
if(temp_lid == curlid){
var del_aw_pos = curid[1];
break;
}
}
del_aw = temp_lid+'#'+del_aw_pos;
var i = 1;
var j =0;
var op = false;
var delpoint;
var endpoint;
var delcatid = '';
var artcounter = 0;
var artcounterArr = new Array();
$(".sortli").each(function (){
var atid = this.id.split('_');
//if(atid[2]!=cat_id)return;
if(this.id == del_aw){
deleted = 'yes';
delcatid = atid[2];
$(this).remove();
op = true;
i=i+1;
delpoint=i-1;
//alert('D'+delpoint);
//return;
}
if(atid[2]==cat_id){endpoint = i-1;artcounter=artcounter+1;}
else if(j==0 && artcounter > 0){
if(artcounter>0)artcounter = artcounter-1;
//else artcounterArr[j] = 0;
artcounterArr[j] = artcounter;
j=j+1;
artcounter = 0;
}
i = i + 1;
});
//alert(delpoint)
//alert(endpoint);
//alert(artcounterArr[0]);
if(op){
for(var k=delpoint; k<counter-1;k++){
var orderVal1 = tempOrderArr[k];
if(k<endpoint)document.getElementById('sortvalid_'+(k+1)).innerHTML = orderVal1;
document.getElementById('sortvalid_'+(k+1)).id = 'sortvalid_'+(k);
document.getElementById('sortdn_'+(k+1)).id = 'sortdn_'+(k);
document.getElementById('sortup_'+(k+1)).id = 'sortup_'+(k);
var t = tempIdArr[(k+1)].split('#');
t=t[0];
document.getElementById(tempIdArr[(k+1)]).id = t+'#'+k;
}
$(".rowHead").each(function (){
var taid = this.id;
var sp = this.id.split("^");
var a1 = sp[1];
//alert(a1);
//alert(cat_id);
if(parseInt(a1)>parseInt(cat_id)){
var a2 = sp[2];
var ta = 'lititle^'+a1+'^';
//alert(ta);
document.getElementById(taid).id = ta+(a2-1);
}
});
var a2temp;
var a1temp;
var delcat=null;
var rowHeadLast;
$(".rowHead").each(function (){
//var taid = this.id;
rowHeadLast = this;
var sp = this.id.split("^");
var a1 = sp[1];
var a2 = sp[2];
if(a2temp == a2 && delcat==null){delcat = a2temp; delcatid=a1temp;}
a2temp = a2;
a1temp = a1;
});
var delok = false;
$(".rowHead").each(function (){
//var taid = this.id;
//alert(deleted);
var sp = this.id.split("^");
var a1 = sp[1];
var a2 = sp[2];
if(delcat == a2 && a1==delcatid && deleted==''){delok= true;deleted='yes';$(this).remove();}
});
//alert(delcatid);
//if(!artcounterArr[0])alert('d');
if(!delok){
$(".rowHead").each(function (){
var sp = this.id.split("^");
var cid_t = sp[1];
if(!artcounterArr[0] && delcatid == cid_t)$(this).remove();
//else if(artcounterArr[0]<=0)$(this).remove();
});
}
if(deleted ==''){
$(rowHeadLast).remove();
}
}
setDivsInArray();
//$(".pleaseWait").dialog("close");
closeLightBox();
}
else if(status == 'DBDelete:error'){
//$('#row_'+artwork_id).fadeOut(3500);
$('#divStatus').fadeIn(500);
$('#divStatus').html('<b>Artwork Delete Error</b>');
$('#divStatus').fadeOut(4500);
}
}
});
}
它很长，我认为如果要求只是在确认弹出框中点击“是”时删除数据，我就不需要所有这些东西
现在这里是删除PHP函数
function deleteArtWork($artwork_id,$category_id){
$artwork_cat_lookup_del = "delete from artwork_category_lookup where artwork_id = '$artwork_id' AND category_id='$category_id'";
if(mysql_query($artwork_cat_lookup_del)){
$userObj = new User();
$allArtWorkByCat = $userObj->allArtWorkByCat($category_id);
for($itr = 0; $itr<count($allArtWorkByCat); $itr++){
$ordr = $itr + 1;
$art_id = $allArtWorkByCat[$itr]['artwork_id'];
$updateSQL = "update artwork_category_lookup set artwork_display_order='$ordr' where artwork_id = '$art_id' AND category_id = '$category_id'";
mysql_query($updateSQL);
}
$action = $userObj->userActions('Artwork id: '.$artwork_id.' is deleted', 'Gallery');
$userObj->setActionintoDB($action);
echo 'done';
}
else echo 'DBDelete:error';
return;
答案 0 :(得分：1)
我认为您不想开始更改上面的代码，因为它用于通过ajax将相关数据传递给php脚本。
您需要的是javascript提示拦截链接点击并为用户提供继续或取消删除操作的选项。这是对的吗？
http://www.tizag.com/javascriptT/javascriptconfirm.php
在“deleteThisArtWork”javascript函数开始时，您需要显示提示。
function deleteThisArtWork(artwork_id){
var answer = confirm("Are you sure you want to delete this record?");
if (answer){
//do the rest of the function as usual, i.e. delete row via ajax.
}else{
return false;
}
}
这应该可以阻止用户意外删除记录，而不必至少不小心点击确认弹出窗口！
如果要使确认弹出窗口中的文本动态化，则需要将动态文本作为变量传递给“deleteThisArtwork”方法，或者使用一些javascript从页面上的其他元素中绘制它。
