js 拼接字符串，table等

var userTableStr = \'\';
userTableStr += \'<table width="750" height="33" border="1">\';
userTableStr += \'<tr>\';
userTableStr += \'<td width="100"><input type="text" size ="11" value=""/></td>\';
userTableStr += \'<td width="100"><input type="text" value="" size ="11"/></td>\';
userTableStr += \'<td width="90"><input type="text" value="" size ="8"/></td>\';
userTableStr += \'<td width="390"><select name="tableColumnsName" id="tableColumnsName" onchange="setDataTypeLength()">\';
userTableStr += \'<option>--请选择--</option>\';
for (var j = 0; j < selecedAllColumns.length; j++) {
    var objcolumns = selecedAllColumns[j].columnName + "," + selecedAllColumns[j].dataType + "," + selecedAllColumns[j].dataLength;
    userTableStr += \'<option value="\' + objcolumns + \'">\' + selecedAllColumns[j].columnName + \'</option>\';
}
userTableStr += \'</select></td>\';
userTableStr += \'<td width="60"><input type="text" value=""/></td>\';
userTableStr += \'<td width="20"><input type="text" value="" size ="3"/></td>\';
userTableStr += \'<td width="93"><input id="primaryKey" type="radio" /></td>\';
userTableStr += \'<td width="93"><input id="defaultValue" type="text" value="" size ="20" /></td>\';
userTableStr += \'</tr>\';
userTableStr += \'</table>\';
showContentObj.innerHTML = showContentObj.innerHTML + userTableStr;

全局就是一个userTableStr的空字符串，一直是+=的形式，把所有想要的表单写好，中间加了一个下拉框的选择，
也可以加上触发函数，都可以加上。再次学习一下：rows[0]["Name"]==rows[0].Name

也可以用Jquery的Append来追加的

$("#div").append("<table><tr align=\'center\'>" + "<td >" + "拼接的DIV内容" + "</td>" + "</tr></table>");

function GetProductOrderInfo(obj) {
    var strhtml = "<ul class=\'artDialogDiv\'>";
    $.each(obj,
    function(i, item) {
        strhtml += "<li>" + item.OrderNo + " <a href=\'/product/OrderIndex\'>查看</a> </li>";
    });
    strhtml += "</ul>";
    return strhtml;
}

（2追加：）$("#pText").append("<span>2222</span>");结果是：<pid="1"><p>1111</p><span>2222</span></p>
