[SalesForce] Pass selected value from html to controller

I have to pass the selected picklist value by user from apex form using <select> and <options> html tag to a standard controllers picklist field.

I am unable to get the values from Page to controller. Please suggest how this can be done.

VF Page

<select class="form-control form-group">
    <option value="">--None--</option>
    <option value="">A</option>
    <option value="">B</option>
    <option value="">C</option>
</select>

<apex:actionFunction name="dfunction" action="{!receiveInput}">
    <apex:param id="dname" name="type" value=""/>
</apex:actionFunction>

<!--Some <button> with onCLick= myfoo() in vf page-->
//Javascript
myfoo(){
    var n3 = document.getElementById("type").value;
    dfunction(n3);
}

Controller

//Controller
public void receiveInput() {
    String input = Apexpages.currentPage().getParameters().get('type');
}

EDIT1-

var n3 = document.getElementById("type").value;
dfunction(n3);
This seems to get the value of option properly but I am not able to get it in my controller.

You need to make following changes in the markup, JS and the controller:

VF Page

<select id="inputSelect" class="form-control form-group">
    <option value="">--None--</option>
    <option value="A">A</option>
    <option value="B">B</option>
    <option value="C">C</option>
</select>

<apex:actionFunction name="dfunction" action="{!receiveInput}">
    <apex:param id="dname" name="type" value=""/>
</apex:actionFunction>

<!--Some <button> with onCLick= myfoo() in vf page-->
//Javascript
myfoo(){
    var n3 = document.getElementById("inputSelect").value;
    dfunction(n3);
}

Controller

//Controller
public void receiveInput() {
    String input = Apexpages.currentPage().getParameters().get('type');
}

[SalesForce] ActionFunction working in Chrome but not in IE and Moz

Try to use jQuery to trigger on the keyPress/keyDown events. Additionally i leave the value parameter empty if i want to set it from another javascript function and use reRender to refresh some areas:

<script>
jQuery('[id$=myField]').on('keydown keypress keyup', function(event) {
    if (event.keyCode == 13) {
        event.preventDefault();
        insertOffer(jQuery(this).val());
    }
});
</script>


<apex:actionFunction name="insertOffer" action="{!setNewBidOffer}" reRender="myField">
     <apex:param name="currOffer" value="" assignTo="{!currentOffer}"/>
</apex:actionFunction>

<apex:inputText value="{!currentOffer}" id="myField"/>

But one thing i don't understand: you trying to set the currentOffer variable to the currentOffer variable?

[SalesForce] Referencing a particular value of a select list

A few things look odd. Instead of using a seprate getter and setter for getRecordType, modify your controller to replace the following:

public String getRecordType() {
    return recType;
}


public void setRecordType(String recType) {
    this.recType= recType;
}

With

public Id recType {get; set;}

Note, I did change the type here to "Id" instead of String. Next, I think {!RecordType} may be a special variable, especially if you are using a standard controller in your visualforce page. So, change the following:

<apex:selectList value="{!RecordType}" multiselect="false" size="1">

to:

<apex:selectList value="{!recType}" multiselect="false" size="1">

Lastly, change your onCreate method to look at recType instead of RecTypeID

public PageReference onCreate(){
    return new PageReference('/a0W/e&RecordType=' + recType);
}

If none of this works, throw some System.debugs in the getter / setters and onCreate method and check your Debug Logs for any errors or indications as to why your code isn't working.
