I have created a custom page item 'tot_credit' to get correct alignment below my tabular form report, using the below code .
,it is written in the region 'footer text'.But I am unable to access this item 'tot_credit' inside my page process(pl/sql code). It is accessible in java script code. what is the solution?
<table>
<tr>
<label>Total Credit</label> <input type="text" style="text-align:right;width:120px" name="tot_credit" id="tot_credit" >
</tr>
</table>
You can't access the item in PL/SQL because you have not defined the item in Apex. You need to define it as an Apex page item, instead of just writing the raw HTML for it.
You are probably not able to access it as the item is declared in page footer, and your pl/sql code is defined before the item declaration. Either moving the item declaration upwards on the page, or defining the pl/sql code in page footer - one of these two should solve your problem.

I am converting a document that is readonly into a one where a user can edit.
Looping the values into a text was possible, my problem is converting those text into fields.
Currently I have the following code in my HTML, whereby the defectDto is the object I am planning on using to capture the fields.
<tr th:each="res, stat : *{response}" th:object="${defectDto}">
<td>
<input type="number" th:field="*{res[__${stat.index}__].defectId}" readonly="true"/>
</td>
...
</tr>
The HTML code above results in a processing error, please see image below:
In Java, I've used the model to bind the list returned (as seen below):
model.addAttribute("response", getDefectMessage.getMessage());
getDefectMessage.getMessage() above is of type List of DefectDto. The sample data is as seen below (please see image).
Being a newbie in Thymeleaf, may I please get assistance in rendering the HTML page without any errors. (Thanks in advance).
I'am currently creating a MVC Java Web App with Struts2.
One element of my app is searching for some results via form. When the user submits the form an Action gets the necessary values from the database and populates a Map:
Map<Integer,List<String>> values = new HashMap<Integer,List<String>>();
Which has a list of column values for each row.
By Following this approach I can have generic JSP for displaying the results of any resultbox:
<s:div cssClass='resultContainer'
cssStyle=' min-height: 150px; max-height:%{header}px; overflow: auto; %{display}; '
theme="qxhtml">
<table id='resultTable'>
<tr id='tableHeader'>
<s:iterator value="headers">
<th><s:property /></th>
</s:iterator>
</tr>
<s:iterator value="values">
<tr class='results'>
<s:iterator value="value">
<td><s:property escape="false" /></td>
</s:iterator>
</tr>
</s:iterator>
</table>
I feel now that this is a bad approach. Instead I should change the Map to a List of ResultBoxRow objects. Each ResultBox will have its own View Jsp instead of one generic one allowing me to iterate over the objects and output for example:
<s:iterator value="value">
<td><s:property name="firstname" /></td>
<td><s:property name="lastname" /></td>
etc.
In the case of the table headers I may need to give certain headers individual style properties. I feel these should be defined in the JSP itself rather than get the JSP to reference a value from the controller containing the style for that header.
I think my overall question is how much should the controller control the style/display of elements of the View? I feel it should just generate the individual elements displayed in the tags but not the values to put in the "style" tag of the row for example. Even if this does sacrifice a simple single JSP to handle every result box.
It would be great to get your opinions.
The controller should have nothing to do with the display mechanism: that's the point of MVC, to completely separate the data from its presentation.
You can still DRY up the view layer via custom tags, includes, templates, etc. Styles may be passed as attributes, while the underlying DOM would be created by a single page or template.
It also matters what the nature of the attributes you want to pass. If they're semantic that could logically from from the model or controller that's fine. If they're purely presentational, like colors, widths, etc. then it has no business in the model or controller.
I am having a problem where I try to render a <table> inside of parent container, but MVC3 Razor always renders the outside of the container tag. This causes problems when trying to control the outside parent container via Javascript.
Razor Example:
<span id="mySpan">
#Html.Action("Table1", "GetMyTable")
</span>
HTML that is output:
<span id="mySpan"></span>
<table>
<thead><tr><th>Header</th></tr></thead>
<tbody>
<tr><td>Foo</td></tr>
<tr><td>Bar</td></tr>
</tbody>
</table>
No matter which parent container I try to stick the table into, a div, span, p, the table always renders OUTSIDE the container's tags! Can anyone explain what I am doing wrong? How should I code the Razor syntax to properly add the table inside those tags?
as you are viewing the output in Firebug, what is happening is you are seeing an "effective" view of the html, after the browser engine has parsed it.
in HTML5, many tags do not need to be explicitly closed. If you include a tag "inside" another that is invalid (like a table inside a span), the browser assumes what you are doing is using an unclosed span tag, so it automatically closes it for you before starting the table tag.
The easiest fix here would be either not to "wrap" the table, or wrap it with something that HTML5 considers valid, such as a section tag.
Another option would be going back to XHTML1.1, where a table is valid inside a div (but not inside a span). Also, XHTML requires explicit closing tags, so this behavior would not show up there. (the same thing for XHTML5, though it's still invalid to wrap a table with a div in XHTML5)
Viewing the raw source would reveal that Razor is not axtually changing anything here; it is the browser. It is good to see this, though; so you know what the browser is expecting and how it's handling what you are sending it.
Is there a visualforce component for links? I'd like a link () on my page which can trigger an ajax call to one of the functions in the controller and rerender an element on the page.
This is how I'm doing it right now, but I don't want it to be a button, I need a link:
There are two standard apex link components, an apex:outputLink and an apex:commandLink. Both render anchor tags in html. From what you are asking, it sounds like need the command link, but I've posted information about both of them here.
You can find out more about them in the Visualforce Developer's Guide.
The apex:outputLink should be used when you want to create a standard hyperlink:
This component is rendered in HTML as an anchor tag
with an href attribute. Like its HTML equivalent, the body of an
is the text or image that displays as the link. To
add query string parameters to a link, use nested
components.
<apex:outputLink value="https://www.salesforce.com"
id="theLink">www.salesforce.com</apex:outputLink>
The example above renders the following HTML:
<a id="theLink" name="theLink"
href="https://www.salesforce.com">www.salesforce.com</a>
The apex:commandLink is probably what you need.
... executes an action defined by a controller, and then either
refreshes the current page, or navigates to a different page based on
the PageReference variable that is returned by the action. An
apex:commandLink component must always be a child of an apex:form
component.
<apex:commandLink action="{!save}" value="Save" id="theCommandLink"/>
The example above renders the following HTML:
<a id="thePage:theForm:theCommandLink" href="#" onclick="generatedJs()">Save</a>
I am having a strange issue in Firefox 3.5.2 with F5 refresh.
Basically, when I focus on an input field and hit f5 the contents of that input field gets copied to the next form field after the F5 refresh.
But, if you inspect the HTML source code, the values are correctly loaded.
I am not having this issue in IE8 or Safari 4.0.3.
The problem does not occur if I do a hard refresh or run window.location.refresh(true).
After F5 Refresh: http://i805.photobucket.com/albums/yy339/abepark/after.jpg
Here's an overview of what's going on.
I believe the thing you should look into is the autocomplete attribute,
you should set it to off on the input box. However be careful since this will trigger two effects.
When you refresh the page it won't remember the old values
The default dropdown of the already used values on that input box will also be disabled.
If you want to keep the second behavior you should set the autocomplete attribute back to on with JS.
Browsers can remember form field contents over a refresh. This can really throw your scripting off if it is relying on the initial value of a field matching what's in the HTML. You could try to prevent it by calling form.reset() at the start.
Different browsers have different strategies for detecting when a form or a field is the same as in the previous page. If you have clashing names, or names that change on reload, it is very possible to end up confusing them. Would have to see some code to work it out for sure.
In the backend, I am using ASP.NET MVC 1.0 with the Spark View engine. When I examine the source code after an F5 refresh in Firefox 3.5.2, the page renders correctly; however, if you look at the page visually the adjacent form field field gets populated with the value from the previous field.
I included enough code so you can just get an idea of what I'm trying to do.
Again, the rendering is fine and the final view/HTML code is fine. It's what I see on the screen that is incorrect. I am using hidden vars; but the issue occurred before using it as well.
Note in the code below, I have 2 distinct ID fields: "date_{projectTask.ProjectTaskId}" and "finishDate_{projectTask.ProjectTaskId}, which gets renders to something like "date_1" and "finishDate_2".
<table>
<for each="ProjectTask projectTask in projectTasksByProjectPhase">
<input type="hidden" value="${projectTask.ProjectTaskId}" />
<tr>
<td class="date">
<div class="box">
<div class="datefield">
<input type="text" id="date_${projectTask.ProjectTaskId}" value="${startDate}" /><button type="button" id="show_${projectTask.ProjectTaskId}" title="Show Calendar"><img src="~/Content/yui/assets/calbtn.gif" width="18" height="18" alt="Calendar" ></button>
</div>
</div>
</td>
<td>
<div class="box">
<div class="datefield">
<input type="text" id="finishDate_${projectTask.ProjectTaskId}" value="${finishDate}" /><button type="button" id="finishShow_${projectTask.ProjectTaskId}" title="Show Calendar"><img src="~/Content/yui/assets/calbtn.gif" width="18" height="18" alt="Calendar" ></button>
</div>
</div>
</td>
</tr>
</for>
</table>
FYI: ${} are used to output variables in the Spark View engine.
I am also using the YUI 2.7 Connection to make Ajax calls to update the datebase for "change" and "enter/tab key press" events. I am able to verify that the AJAX calls are made correctly and the form field values are still valid.
The problem occurs when I just do a F5 refresh; for some reason, the "finishDate_1" gets populated with the value from "date_1".
This problem occurs just by clicking on "date_1" and hitting F5; so, the adjacent field just gets populated even if there are no AJAX calls.
Here's the Javascript code I call towards the end of the body"
YAHOO.util.Event.onDOMReady(
function() {
var idList = YAHOO.util.Dom.getElementsBy(function (el) { return (el.type == 'hidden'); }, 'input');
len = idList.length;
var startDatePickers = new Array();
var finishDatePickers = new Array();
for (var i = 0; i < len; i++) {
var id = idList[i].value
startDatePickers[i] = new DatePicker("date_" + id, "show_" + id, "cal_" + id);
startDatePickers[i].valueChanged.subscribe(updateDate, 'S');
finishDatePickers[i] = new DatePicker("finishDate_" + id, "finishShow_" + id, "finishCal_" + id);
finishDatePickers[i].valueChanged.subscribe(updateDate, 'F');
}
}
}
The form field gets copied over before any Javascript code is processed because I call the Javascript code towards the end of the body after all HTML is rendered. So, I'm guessing it's a refresh issue in Firefox? What do you guys think?
As you can see above, I created my own calender date picker objects which allows you to either enter the date in the text manually or by clicking on a button to view the calendar and select a date. Once you enter or select the date, an AJAX call will be made to update the datebase in the back end.
Thanks everybody for the quick responses.
#Anonymous: whoever you are, you are awesome!
#bobince: thanks for the feedback as well.
I added a dummy form tag with the attribute autocomplete="off" and that solved the problem!
I was scratching my head because I didn't get this issue in Safari 4.0.3 or Internet Explorer 8.
<form action="" autcomplete="off">
<!-- my code -->
</form>
The values were loading correctly in the back end (ASP.NET MVC 1.0/Spark View engine) and the HTML source code reflected this, but the input field values were not getting populated correctly. I was using the YUI Connection Manager and Javascript to support edit-in-place and the date pickers.
I tried changing the XHR call to a GET call instead of POST and the same issue was happening.
Anyway, the problem was that the Firefox was not setting the correct values for the input fields for F5 refreshes.
Again, thanks so much! You guys rock!
All element id's must be unique, if two elements have same id's then that could be reason why Firefox inserts same values to elments that didn't orginally have those values entered.
I had a similar problem related to my question at Input control shows incorrect value, even 'though inspect element shows the right value is there
The problem occurred for me in Firefox, but not Chrome, for some but not all controls on the form, and when I pressed F5, but not ctrl-F5.
The "dummy form" seems to have resolved it for me.
