I have a VisualForce input text box:

            <apex:inputText value="{!Address1}" id="Example1TextBox" html-placeholder="Example 1"/><br></br>

In the controller class I have:

public string Address1{
        Id myId = ApexPages.currentPage().getParameters().get('id');
        FedExLabelMethods job = new FedExLabelMethods();
        String AddressValue;
        List<String> compressedAddresses = FedExLabelMethods.getlistofAddresses(myId);
        for(integer i=0; i < compressedAddresses.size(); i++){
            String temp = compressedAddresses[i];
                string[] temparray = temp.split(',');
                AddressValue = temparray[1];
                AddressValue = AddressValue.substring(1);
                i = i + 10000000;
            } else {
        if (AddressValue == 'null'){
            AddressValue = '';
        return AddressValue;

Which is referencing a select list. Essentially the textbox will display a query value for whatever the selectlist has currently selected. However I have a problem: If the select list has nothing selected, or even if it does have something selected, and I want to change the value of the text box manually, then when the form is re-rendered it references the selectlist again and deletes whatever is in it to comply to the code.

Essentially, the text box only listens to the selectlist, whereas I want it to be somewhat like:

IF the textbox has text in it, THEN ignore the query and just set the text that is currently in it.

Is it possible to do this?

EDIT: By the way, the selectlist rerenders the form but I'm figuring i'll need to either add an actionsupport to the textbox to rerender the form or a button, I'm fine with either one.

  • Not directly related to your question, but if you want to make your code more readable and shorter, you can use the 'foreach' syntax (for (String temp: compressedAddresses)), remove the 'else' block, and instead of doing i + 10000000 (very ugly), just use break;

At the beginning of the get section of the string:

if(Address1 != null){
            AddressValue = ApexPages.currentPage().getParameters().get('Address1');

then put all of the current code in the else statement and return the addressvalue!

Make sure to check and see if the selectlist is custom


I would use this address value inside a javascript block on the page and use it to fill the value of the input IF needed. ie:


    var address1 = '{!Address1}';
    var inputElements = document.getElementsByClassName('yourClass');
    var inputElement = inputElements[0];
    //you will have to verify that this works - this is just example code

    if (!inputElement.value){
        inputElement.value = address1;

You can make sure this gets rerendered also by putting it in the page in an apex element.

Hope this helps.
