Jquery Number Is Not A Function
event that updates a form, and in the updating process it calls a function to calculate shipping. I'm not sure why, but I'm getting the following error when I try to call the function: Uncaught TypeError: number is not a function The function, shipping, looks like this: function shipping( weight ) { var flat switch( weight ) { case 1: case 2: case 3: flat = 32.00; break; case 4: flat = 18.50; break; uncaught typeerror undefined is not a function case 5: flat = 15.80; break; case 6: flat = 14.00; break; case 7: flat = 12.71; break; case 8: flat = 11.75; break; case 9: flat = 11.00; break; case 10: flat = 10.40; break; case 11: flat = 9.91; break; case 12: flat = 9.50; break; case 13: flat = 9.15; break; case 14: flat = 8.86; break; case 15: flat = 8.86; break; case 16: flat = 8.38; break; case 17: flat = 8.18; break; case 18: flat = 8.00; break; case 19: flat = 7.84; break; case 20: flat = 7.70; break; } // switch var flat_fee = flat * weight; var mile_fee = distance * 0.90; var shipping_fee = flat_fee + mile_fee; simpleCart.shippingTest = shipping_fee; return shipping_fee; } // shipping I'm passing in 1 right now. The variable distance is coming from an ajax call that is completed before this function is run. That function looks like this: function get_distance( zip ) { $.getJSON( 'distance.php', { zip:zip }, function(json) { distance = json }) } // get_distance I've checked to make sure the variable distance is set. The console says the uncaught type error is happing at the line where I call shipping(1). Any thoughts as to why that's happening? javascript share|improve this question asked Jul 26 '10 at 4:02 hookedonwinter 6,089104066 add a comment|

What went wrong? It was attempted to call a value like a function, but the value is not actually a function. Some code expects you to provide a function, but that didn't happen. Maybe there is a typo in the function name? Maybe the object you are calling the method on does not have this function? For example, JavaScript objects have no map function, but JavaScript Array object do. There are many built-in functions in need of a (callback) function. You will have to provide a function in order to have these methods working properly: When working with Array or TypedArray objects: Array.prototype.every(), Array.prototype.some(), Array.prototype.forEach(), Array.prototype.map(), Array.prototype.filter(), Array.prototype.reduce(), Array.prototype.reduceRight(), Array.prototype.find() When working with Map and Set objects: Map.prototype.forEach() and Set.prototype.forEach() Examples A typo in the function name In this case, which happens way too often, there is a typo in the metho
Forum View Course 3683 points Submitted by Judy about 3 years ago Type Errors - learn how to fix these You will encounter several categories of error messages as you learn to write JavaScript code. Reference Errors: you will get these when you try to use (reference) a non-existant variable Syntax Errors: you will get one of these when the structure of one of your JavaScript statements violates the syntactic rules - think of these as bad grammar Type Errors: these show up when a value is not the expected type In the sections below you will find the different Type Errors you may encounter. If you want to talk about concepts or "next steps" or anything general, head over to the Groups page and join in one of the already existing discussions or start your own. Checkout the "Guidelines" post that is pinned in most groups to see if you've found a group that appeals to you. 1 vote permalink TypeError related to console.log() Error message: "TypeError: Property 'log' of object # is not a function" (Chrome) "TypeError: console.log is not a function" (Firefox) "TypeError: 'your string' is not a function (evaluating 'console.log("your string")')" (Safari) "TypeError: Function expected" (IE) What has gone wrong? You have changed console.log() from a function into a string or a number. Explanation: console.log() is a function, it will log/print on the console/screen the message or value you put in the ( ). console.log() is not a variable - it is not expected that you will want to make console.log() EQUAL to something. The interpreter won't stop you from doing so but you should understand the consequences. At some point recently, you ran your code with a statement resembling this: console.log = "You are allowed to play."; console.log = 18; It may not have been one of those exact values but somewhere you told the interpreter to make console.log equal to something. You assigned a new value to console.log(). The result of doing so was that the usual code that is invoked when you use the console.log() function was overwritten by whatever it was you put on the right hand side of the = sign. Normally console.log() is a function but now you have tur
