我正在絞盡腦汁,我需要通過jquery發送一個搜索值,以便在數據庫中進行全文搜索,然後將其顯示在div元素中。我需要在類別表和子類別表中搜索值。我想不出來,我認爲最好的辦法是,如果我發佈兩次(首先搜索類別,其次搜索子策略)。函數search_fulltext返回二維數組。從jquery post返回二維數組
我在想這樣的事情(我知道這並不工作,但只是想證明我多麼希望它的工作,我不知道如何使用二維數組處理)
// SCRIPT
function onclick_search_button(searching_value, at)
{
// first post to search in categories
$.post("search.php", {what:searching_value, where: at}, function(data,status){
// echo list of found results in CATEGORIES
var found_items = eval(data);
for(var i=0; i<found_items.length; i++)
{
$result = "Found in category: " + found_items[i]["cat_name"] + "and ID is: " + items[i]["cat_id"] + "</br>";
$("#final_div_results").append($result);
}
// second post to search in subcategories
$.post("search.php", {what:searching_value}, function(data,status){
// echo list of found results in CATEGORIES
var found_items = eval(data);
for(var i=0; i<found_items.length; i++)
{
$result = "Found in category: " + found_items[i]["sub_cat_name"] + "and ID is: " + items[i]["cat_id"] + "</br>";
$("#final_div_results").append($result);
}
}
// search.php中FILE
<?
$inst = new DbQuery();
$what = $_POST["what"];
$where = $_POST["at"];
$result = $inst->search_fulltext($what, $where);
// BUT SEARCH_FULLTEXT RETURNS TWO-DIMENSIONAL ARRAY SO I GUESS I CANNOT USE THE FOLLOWING
echo json_encode($result);
?>
// HTML DIV
<div id="final_div_results">These are the results</div>
'json_encode'對於2d數組非常有效。附: *不要*做'eval(數據)'!在你的'$ .post'中添加''json''作爲第四個參數:'$ .post(「search.php」,{your:data},function(found_items){},'json');'。 –
