AJAX submit on enter textfield

[lhemingway]

I am using the following code from a third party script which I purchased.

 

At the moment there is a "save" button which submits what is in the text field of an ajax table. I am wanting to change it to on enter submit the data.

How can I modify the following code to do so.

//Declare Some Global Variables
var cancelString;
var editTblRow;
var editTblCell;
var editSQLRowID;
var editKey;
var editCancel;

function showDelete(id) {
$("#del_" + id).toggle();
}

function loadTable(){
	$("#ajaxTable").load("table.php");
}

function insertRow(){
$("#ajaxTable").load("dbFunc.php?action=new");
}

function selectTable(optvalue){
		editTblRow = null;
		editTblCell = null;
		$("#active_table").val(optvalue);
	$("#ajaxTable").load("table.php?table=" + optvalue);
}

function loadingTimer(){
	$("#ajax_loading_div")
	.bind("ajaxSend", function(){
	$(this).show();
	})
	.bind("ajaxComplete", function(){
	$(this).hide();
	});
}

function delRow(thisRow,rowID){
	var delConfirm = confirm("Delete this row?");
	if (delConfirm){
	$.get("dbFunc.php", { action: 'delete', rowid: rowID },
	function(data){
	$(thisRow).parent().fadeOut(500, function() {$(thisRow).remove(); });
	}); }
}

function cancelInsert(rowID){
	$.get("dbFunc.php", { action: 'delete', rowid: rowID },
	function(data){
	loadTable();
	}); 
}

function toggleDelRow(rowid){
	$("#"+rowid).toggle();
}

function searchTable(searchTerm){
loadingTimer();
	$("#ajaxTable").load("table.php?search=" + encodeURI(searchTerm) + "&table=" + $('#active_table').val());
}

function gotoStart(start){
loadingTimer();
var search_text = '';
if($("#searchText").val()!='Search'){search_text=$("#searchText").val()}
	$("#ajaxTable").load("table.php?start=" + start + "&search=" + search_text + "&table=" + $('#active_table').val());
}

function sortTable(order_by,direction){
loadingTimer();
var search_text = '';
if($("#searchText").val()!='Search'){search_text=$("#searchText").val()}
	$("#ajaxTable").load("table.php?start=0&search=" + search_text + "&order_by=" + order_by + "&direction=" + direction + "&table=" + $('#active_table').val());
	$("#" + order_by).attr("src","img' + '../img/ajax/arrow_down.gif");
}


this.label2value = function(){	
	var inactive = "inactive";
	var active = "active";
	var focused = "focused";
	
	$("label").each(function(){		
		obj = document.getElementById($(this).attr("for"));
	if($(this).attr("for")=="searchText"){
		if(($(obj).attr("type") == "text") || (obj.tagName.toLowerCase() == "textarea")){			
			$(obj).addClass(inactive);			
			var text = $(this).text();
			$(this).css("display","none");			
			$(obj).val(text);
			$(obj).focus(function(){	
				$(this).addClass(focused);
				$(this).removeClass(inactive);
				$(this).removeClass(active);								  
				if($(this).val() == text) $(this).val("");
			});	
			$(obj).blur(function(){	
				$(this).removeClass(focused);													 
				if($(this).val() == "") {
					$(this).val(text);
					$(this).addClass(inactive);
				} else {
					$(this).addClass(active);		
				};				
			});				
		};	
	};
	});		
};
