Calling a bean method from an onClick event
Hello,
I have a dataTable with an HtmlInputText on each cell, i want to add
an onClick event for each inputText, so when i click on it, the values
changes to a value stored on backbean, and when i clickout the old
value comes again.
The inputText have an setOnClick(String) method, but how can i get the
bean value through a javascript function? i wanted to do something
like:
[code]dataTable.setVar("myItem");
dataTableMatriz.setValue(matriz); // ArrayList of ArrayLists
ValueBinding myItem =
FacesContext.getCurrentInstance().getApplication().createValueBinding("#{myItem.get("
+ i + ").valueX}");
input.setValueBinding("value", myItem);
inputText.setOnClick("this.value = " + *set to a valueY just while
selected* ";");
input.setOnblur("this.value = " + *set again to valueX* ";");[/code]
Any idea how to get this?
Thanks

Hi Nuno,
you either have to make a "submit" to your form and use a
ValueChangeListener for your input element or use an Ajax framwork like
Richfaces (http://www.jboss.org/jbossrichfaces/).
By the way: Your java script function seems to be missing a closing
brace: It should be something like:
input.setOnclick("alert('#{myBackingBean.randomVar}')");
Cheers,
Christopher

Thanks for your answer, but i couldn't solve my problem.
I have me table defined on backbean and on my inputText if i put something like:
input.setOnclick("alert('#{myBackingBean.randomVar}'");
I get an alert with the message: #{myBackingBean.randomVar}
If i remove the ' ' before and after #{myBackingBean.randomVar}
It gives me an javascript error, saying me that it's not defined or something
Any ideas?

Re: Calling a bean method from an onClick event

I've passed el expressions into a function like this on my page code.
I'm using facelets, but I don't think it makes any difference.
rowOnClick="colorizeRow('#{routeSplitReorderPage.routeTableDataOne.uiDataClientId}',
'#{routeSplitReorderPage.routeTableDataOne.selectedRowInputClientId}',
this.id, '#{rowIndex}');"

If you don't like that approach for some reason, take a look at the
thread named "How to get value from managed bean by JavaScript" from
April 2007 -- there's a number of other approaches mentioned in
response to that question.
