我有一個自動完成組合框,其中包含供應商列表,當選擇一個項目時,它會將該ID存儲在會話和隱藏字段中。如何使用Jquery和PHP分配會話變量?
這裏是我當前的代碼:
<script>
(function($) {
$.widget("ui.combobox", {
_create: function() {
var self = this,
select = this.element.hide(),
selected = select.children(":selected"),
value = selected.val() ? selected.text() : "";
var input = this.input = $("<input>")
.insertAfter(select)
.val(value)
.autocomplete({
delay: 0,
minLength: 0,
source: function(request, response) {
var matcher = new RegExp($.ui.autocomplete.escapeRegex(request.term), "i");
response(select.children("option").map(function() {
var text = $(this).text();
if (this.value && (!request.term || matcher.test(text)))
return {
label: text.replace(
new RegExp(
"(?![^&;]+;)(?!<[^<>]*)(" +
$.ui.autocomplete.escapeRegex(request.term) +
")(?![^<>]*>)(?![^&;]+;)", "gi"
), "<strong>$1</strong>"),
value: text,
option: this
};
}));
},
select: function(event, ui) {
ui.item.option.selected = true;
self._trigger("selected", event, {
item: ui.item.option
});
},
change: function(event, ui) {
if (!ui.item) {
var matcher = new RegExp("^" + $.ui.autocomplete.escapeRegex($(this).val()) + "$", "i"),
valid = false;
select.children("option").each(function() {
if ($(this).text().match(matcher)) {
this.selected = valid = true;
return false;
}
});
if (!valid) {
// remove invalid value, as it didn't match anything
$(this).val("");
select.val("");
input.data("autocomplete").term = "";
return false;
}
}
}
})
.addClass("ui-widget ui-widget-content ui-corner-left");
input.data("autocomplete")._renderItem = function(ul, item) {
return $("<li></li>")
.data("item.autocomplete", item)
.append("<a>" + item.label + "</a>")
.appendTo(ul);
};
this.button = $("<button type='button'> </button>")
.attr("tabIndex", -1)
.attr("title", "Show All Items")
.insertAfter(input)
.button({
icons: {
primary: "ui-icon-triangle-1-s"
},
text: false
})
.removeClass("ui-corner-all")
.addClass("ui-corner-right ui-button-icon")
.click(function() {
// close if already visible
if (input.autocomplete("widget").is(":visible")) {
input.autocomplete("close");
return;
}
// work around a bug (likely same cause as #5265)
$(this).blur();
// pass empty string as value to search for, displaying all results
input.autocomplete("search", "");
input.focus();
});
},
destroy: function() {
this.input.remove();
this.button.remove();
this.element.show();
$.Widget.prototype.destroy.call(this);
}
});
})(jQuery);
$(function() {
$("#combobox").combobox();
$("#toggle").click(function() {
$("#combobox").toggle();
});
});
</script>
<form method="post">
<p>Choose Supplier:<select name="SupplierDDL" id="combobox">
<input type="hidden" name="SupplierId">
<option value=""></option>
<?php include 'loadSuppliers.php'; ?>
</select><p>
<p>Number of Items:</label><input type="text" name="ItemsQty"/></p>
<input name="SupplierSubmit" type="submit" value='Submit'>
</form>
<script>
$('input[placeholder], textarea[placeholder]').placeholder();
</script>
此外,如果你能就如何使用jQuery回發,因爲我可能會在我試圖創建應用程序的下一部分使用它的例子。
先生/女士您的答案將是非常有益的,非常感謝。
在PHP我可以寫類似$ _SESSION ['name'] =「randel」,現在我想要做的是將自動完成組合框中選擇的id或值存儲在$ _SESSION ['Suppl ierID'] =所選值,同時將值存儲在隱藏字段中。謝謝您的即時答覆,先生。 – 2012-02-20 11:25:39
啊現在我明白你的問題了:)稍後我會編輯我的答案 – giorgio 2012-02-20 11:31:05
由於某種原因,它不工作,我創建了php文件並將$ .get放在腳本的change事件中。 – 2012-02-20 14:52:04
