Description

Removes an element from a structure.

Returns

Returns true, if an element is deleted successfully. False, otherwise.

Syntax

StructDelete(structure, key [, indicatenotexisting ])

StructDelete(structure, key [, indicatenotexisting ])

Parameters

Parameter	Description
structure	Structure or a variable that contains one. Contains element to remove.
key	Element to remove.
indicatenotexisting	True: returns Yes if key exists; No if it does not. False: returns Yes regardless of whether key exists. Default.

Example

myStruct={a:1,b:2,c:3,d:4,e:5};

WriteOutput("The input struct is:");

WriteDump(myStruct);

xFalse=StructDelete(myStruct,"f",false);// Returns Yes regardless of whether key exists

WriteOutput(xFalse & " | "); //Display Yes

xTrue=StructDelete(myStruct,"f","true");// Returns No since the key "f" does not exist in the input struct

WriteOutput(xTrue & " | "); //Display No

// Delete an element that actually exists in the input structure

StructDelete(myStruct,"e",true); // Deletes element "e" from the struct and returns Yes

WriteOutput("The updated struct is:");

WriteDump(myStruct);

</cfscript>

<cfscript> myStruct={a:1,b:2,c:3,d:4,e:5}; WriteOutput("The input struct is:"); WriteDump(myStruct); xFalse=StructDelete(myStruct,"f",false);// Returns Yes regardless of whether key exists WriteOutput(xFalse & " | "); //Display Yes xTrue=StructDelete(myStruct,"f","true");// Returns No since the key "f" does not exist in the input struct WriteOutput(xTrue & " | "); //Display No // Delete an element that actually exists in the input structure StructDelete(myStruct,"e",true); // Deletes element "e" from the struct and returns Yes WriteOutput("The updated struct is:"); WriteDump(myStruct); </cfscript>

<cfscript>
       myStruct={a:1,b:2,c:3,d:4,e:5};
       WriteOutput("The input struct is:");
       WriteDump(myStruct);
       xFalse=StructDelete(myStruct,"f",false);// Returns Yes regardless of whether key exists
       WriteOutput(xFalse & " | "); //Display Yes
       xTrue=StructDelete(myStruct,"f","true");// Returns No since the key "f" does not exist in the input struct
       WriteOutput(xTrue & " | "); //Display No
       // Delete an element that actually exists in the input structure
       StructDelete(myStruct,"e",true); // Deletes element "e" from the struct and returns Yes
       WriteOutput("The updated struct is:");
       WriteDump(myStruct);
</cfscript>

Output

Using member function

myStruct={a:1,b:2,c:3,d:4,e:5};

WriteOutput(myStruct.delete("c",true));

</cfscript>

<cfscript> myStruct={a:1,b:2,c:3,d:4,e:5}; WriteOutput(myStruct.delete("c",true)); </cfscript>

<cfscript>
       myStruct={a:1,b:2,c:3,d:4,e:5};
