Javascript Substring() Function Cross-Browser Differences

I found something interesting while working on some Javascript form submission code. The problem was that the form was only submitting in IE and not in FireFox. After some troubleshooting I was able to determine that the Substring function is different between the two browsers. Here is an example if you want to give it a try. <script language='javascript' type='text/javascript'> function controlSubmit(obj,act) {    obj.action = act;    alert(obj.action.substring(0,13));    if (obj.action.substring(0,13) == 'action.cfm') obj.submit(); } </script> <form>    <input type="button" value="one" onclick="controlSubmit(this.form,'admin.cfm');">    <input type="button" value="two" onclick="controlSubmit(this.form,'action.cfm');"> </form> You will notice that the first button will only display an alert on both browsers and the second button will display an alert ...

Combining Select and Insert into the same CFQuery tag

So you want to grab some values and insert them into a table. Here is the hard way. <cfquery name="selectQuery" datasource="#application.dsn.db2#">     SELECT Setting1,Setting2,Setting3     FROM defaultSettings     WHERE ID = 101 </cfquery> <cfquery name="insertQuery" datasource="#application.dsn.db#"> INSERT INTO Settings     (TS,     Name,     Setting1,     Setting2,     Setting3) VALUES(GetDate(),     'Test',     <cfqueryparam cfsqltype="cf_sql_varchar" value="#selectQuery.Setting1#">,     <cfqueryparam cfsqltype="cf_sql_varchar" value="#selectQuery.Setting2#">,     <cfqueryparam cfsqltype="cf_sql_varchar" value="#selectQuery.Setting3#">) </cfquery> Here is the easier way, combining both Select and Insert i...

Using SQL's Scope_Identity

So you want to get the ID(PrimaryKey) of the last record inserted into the database without having to do a second cfquery block. Here is an example of doing it the hard way. <cfset value1 = 2007> <cfset myuuid = CreateUUID()> <cfquery name="insert" datasource="#APPLICATION.DSN.DB#">     INSERT INTO table(column1,column2)     VALUES(#VARIABLES.value1#, '#VARIABLES.myUUID#') </cfquery> <cfquery name="select" datasource="#APPLICATION.DSN.DB#">     SELECT ID     FROM table     WHERE column2=<cfqueryparam cfsqltype="cf_sql_varchar" value="#VARIABLES.myUUID#"/> </cfquery> You would then reference the ID as select.ID. The easier way. <cfquery name="insert" datasource="#APPLICATION.DSN.DB#">     INSERT INTO table(column1,column2)     VALUES(#VARIABLES.value1#, '#VARIABLES.myUUID#')     SELE...
