Using PrimeFaces 6, I am trying to filter my p:selectOneMenu when the user paste a value or when the user delete a value using CTRL + Backspace, in another word, when the value got changed anyhow.
Please find my below code.
<p:selectOneMenu id="providerURLDD" widgetVar="providerURLDD"
value="#{switchProviderBean.selectedProvider}"
panelStyle="width:240px" effect="fade" filter="true"
style="width:240px" filterMatchMode="contains"
required="true"
requiredMessage="#{msg['selectProvider']}">
<f:selectItem itemLabel="Select" />
<f:selectItems value="#{switchProviderBean.providerAccounts}"
var="providerAcc"
itemLabel="#{providerAcc.code}-#{providerAcc.switchAccountId}-#{providerAcc.name}"
itemValue="#{providerAcc.switchAccountId}" />
</p:selectOneMenu>
I also tried to use Javascript like this:
function getTextAreaSelection(textarea) {
var start = textarea.selectionStart,
end = textarea.selectionEnd;
return {
start: start,
end: end,
length: end - start,
text: textarea.value.slice(start, end)
};
}
function detectPaste(textarea, callback) {
textarea.onpaste = function() {
var sel = getTextAreaSelection(textarea);
var initialLength = textarea.value.length;
window.setTimeout(function() {
var val = textarea.value;
var pastedTextLength = val.length - (initialLength - sel.length);
var end = sel.start + pastedTextLength;
callback({
start: sel.start,
end: end,
length: pastedTextLength,
text: val.slice(sel.start, end)
});
}, 1);
};
}
var textarea = document.getElementById("switchProviderChoice:providerURLDD_filter");
detectPaste(textarea, function(pasteInfo) {
console.log('perform filter');
PF('providerURLDD').filter();
});

The issue is that your Delete Controller method is calling View() at the end. That method will attempt to find a view file with the name of the controller method. If you want to show the list of files after the delete you can redirect to your index action like this:
[HttpGet]
public ActionResult Delete(string deletedfile)
{
string current_usr = User.Identity.GetUserId();
string fullPath = Request.MapPath("~/Files/" + current_usr + "/" + deletedfile);
if (System.IO.File.Exists(fullPath))
{
System.IO.File.Delete(fullPath);
ViewBag.Message = "Deleted";
}
return RedirectToAction("Index");
}
See this link from the microsoft Docs for more detail on redirecting
https://learn.microsoft.com/en-us/aspnet/mvc/overview/older-versions-1/views/asp-net-mvc-views-overview-cs
I would like to add filter for JSF table and limit the values based on filter value.
<h:inputText id="search" value="#{accounts.searchString}"></h:inputText>
<h:commandButton value="Search" action="#{accounts.search()}">
<f:ajax execute="search" render="output"></f:ajax>
</h:commandButton>
I suppose that the best way will be to add the filter value into the SQL query:
SELECT * FROM CUSTOMERS ORDER BY %S %S offset ? limit ?
Full code: http://pastebin.com/eEeTWEqK
How I can implement this for the code into the link?
PS. I modified the code this way:
<div class="div_input_style">
<h:inputText id="search" class="input_style" value="#{accounts.searchString}"></h:inputText>
<h:commandButton class="theSpan" value="Search by title">
<f:ajax execute="search" render="output"></f:ajax>
</h:commandButton>
</div>
public List<AccountsObj> list(int firstRow, int rowCount, String sortField, boolean sortAscending) throws SQLException
{
String SqlStatement = null;
if (ds == null)
{
throw new SQLException();
}
Connection conn = ds.getConnection();
if (conn == null)
{
throw new SQLException();
}
String sortDirection = sortAscending ? "ASC" : "DESC";
SqlStatement = "SELECT * FROM ACCOUNT "
+ " WHERE ? IS NULL OR ? IN (USER_NAME, FIRST_NAME, LAST_NAME)"
+ " ORDER BY %S %S offset ? limit ? ";
String sql = String.format(SqlStatement, sortField, sortDirection);
PreparedStatement ps = null;
ResultSet resultSet = null;
List<AccountsObj> resultList = new ArrayList<>();
try
{
conn.setAutoCommit(false);
boolean committed = false;
ps = conn.prepareStatement(sql);
ps.setString(1, searchString);
ps.setString(2, searchString);
ps.setInt(3, firstRow);
ps.setInt(4, rowCount);
resultSet = ps.executeQuery();
resultList = ProcessorArrayList(resultSet);
conn.commit();
committed = true;
}
finally
{
ps.close();
conn.close();
}
return resultList;
}

You don't update content you want to be refreshed.
<p:ajax event="select" listener="#{searchContent.onNodeSelect}" update="form:fileData"/>
Add id to your h:outputText
<p:layoutUnit position="center">
<h:outputText id="fileData" value="#{searchContent.fileData}" />
</p:layoutUnit>
