Use String.contains in an Apex page

Question

<apex:outputField rendered="{!(WidgetType.contains('mywidget1'))}" />

When I do this I get an error...

Error: Unknown function WidgetType.contains. Check spelling

... even though the WidgetType returns a String!

It will let me do this though...

rendered="{!(WidgetType == 'mywidget1')}"

Here is the property in the controller...

public String getWidgetType() {

    return Settings.getWidgetType();

}

Description

Compares two arguments of text and returns TRUE if the first argument contains the second argument. If not, returns FALSE.

The following example checks the content of a custom text field named Product_Type and returns “Parts” for any product with the word “part” in it. Otherwise, it returns “Service.” 

{!IF(contains(opportunity.Product_Type__c, "part"), "Parts", "Service")}

This function is case sensitive so be sure your compare_text value has the correct capitalization.

Use

CONTAINS(text, compare_text) and replace text with the text that contains the value of compare_text.
