[英]Auto refresh select box when new option added to it
I am facing a problem when I add data to my select box at run time the page never auto refreshes. 当我在运行时将数据添加到选择框时,页面无法自动刷新时遇到了问题。 I have to manually refresh the page in order to get select picker populated with newly added option value.
我必须手动刷新页面,才能用新添加的选项值填充选择器。
Now when I click ... dotted button in select picker it opens a popup 现在,当我单击“选择器”中的“ ...”虚线按钮时,将打开一个弹出窗口
If i add value on this popup it does not gets reflected in my selectpicker. 如果我在此弹出窗口中添加值,则不会反映在我的选择器中。 Please help me.
请帮我。 I want to auto refresh select box
我想自动刷新选择框
EDIT: MY JSP CODE: 编辑:我的JSP代码:
<TD ALIGN="LEFT">
<fdms:speedselect name="firstCallInformation" property="placeDeath" category="LOCDEATH" column="1"
combo="true" maxlength="50" size="1" textsize="30">
<fdms:linkoption text="Edit list..." script="tableWindow2('LOCDEATH',1,'firstCallInformation.placeDeath')" />
<fdms:targetfield column="2" property="locationDeceased" />
<fdms:targetfield column="3" property="placeDeathCity" />
<fdms:targetfield column="6" property="placeDeathState" />
<fdms:targetfield column="7" property="placeDeathZip" />
<fdms:targetfield column="8" property="locDeathLicenseNumber" />
</fdms:speedselect>
</TD>
I am using sort of ajax call but not sure is it correct or not 我正在使用某种ajax调用,但不确定是否正确
function loadFacility(callback)
{
alert('In loadFacility');
var xmlhttp;
var keys=document.firstCallInformation.facilityselect.value;
var urls="localhost:8080/webfdms/showFirstCallInformation.do?vitalsId=366";
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status == 200)
{
//var some=xmlhttp.responseXML.documentElement;
var resposne = xmlhttp.responseText;
alert(resposne);
callback(xmlhttp.responseText);
}
}
xmlhttp.open("GET",urls,true);
xmlhttp.send(null);
}
function loadFacilityCallback(resposne){
if(resposne != null){
alert(resposne);
}
}
And calling it like : 并像这样调用它:
<fdms:speedselect property="facility" category="FacilityPlace" maxlength="50" column="1" combo="true" size="1" textsize="60" onchange="loadFacility(callback)">
I'm guessing the update is done on the server? 我猜测更新已在服务器上完成? The jsp will be compiled into a servlet that will render a HTML page, which in turn will live on the browser.
该jsp将被编译到一个servlet中,该servlet将呈现HTML页面,而该页面又将存在于浏览器中。 HTTP is a stateless protocol, so without a further request the jsp page will not know that the change has been made.
HTTP是无状态协议,因此,在没有其他请求的情况下,jsp页面将不会知道已进行更改。
