Title: Solved Javascript error Last modified: December 14, 2017 --- # Solved Javascript error * [cramaekers](https://wordpress.org/support/users/cramaekers/) * (@cramaekers) * [8 years, 5 months ago](https://wordpress.org/support/topic/solved-javascript-error/) * Being that this plugin is no longer supported, I figured I’d post my solution for a Javascript error that this plugin was throwing. My error was: * Uncaught TypeError: Cannot read property ’64’ of undefined in gf-repeater.min. js. * I fixed this error by changing lines 286-288 in class-gf-field-repeater.php to: * ``` if (empty($value)) { $value = array(); $value['formId'] = $form_id; ``` * The addition of `$value = array();` is the fix. * Hope this helps someone! - This topic was modified 8 years, 5 months ago by [cramaekers](https://wordpress.org/support/users/cramaekers/). - This topic was modified 8 years, 5 months ago by [cramaekers](https://wordpress.org/support/users/cramaekers/).

(main.js:69) at HTMLSpanElement.dispatch (jquery-1.8.3.min.js:2) at HTMLSpanElement.u (jquery-1.8.3.min.js:2) ``` * Now, I added this : * ``` if (empty($value)) { $value = array(); $value['formId'] = $form_id; ``` * But the error is still the same. * The Begin repeater has Repeater : ID field 1 The end repeater has Repeater : ID field 3 * Now, in the console, I’ve tried to look what is in gfRepeater_repeaters and this is what showed up : * ``` console.log(gfRepeater_repeaters) VM3008:1 {}__proto__: Objectconstructor: ƒ Object()arguments: (...)assign: ƒ assign()caller: (...)create: ƒ create()defineProperties: ƒ defineProperties()defineProperty: ƒ defineProperty()entries: ƒ entries()freeze: ƒ freeze()getOwnPropertyDescriptor: ƒ getOwnPropertyDescriptor()getOwnPropertyDescriptors: ƒ getOwnPropertyDescriptors()getOwnPropertyNames: ƒ getOwnPropertyNames()getOwnPropertySymbols: ƒ getOwnPropertySymbols()getPrototypeOf: ƒ getPrototypeOf()is: ƒ is()isExtensible: ƒ isExtensible()isFrozen: ƒ isFrozen()isSealed: ƒ isSealed()keys: ƒ keys()length: 1name: "Object"preventExtensions: ƒ preventExtensions()prototype: {constructor: ƒ, __defineGetter__: ƒ, __defineSetter__: ƒ, hasOwnProperty: ƒ, __lookupGetter__: ƒ, …}seal: ƒ seal()setPrototypeOf: ƒ setPrototypeOf()values: ƒ values()arguments: (...)caller: (...)length: 1name: "values"__proto__: ƒ ()Scopes: Scopes[0]No properties__proto__: ƒ ()Scopes: Scopes[0]hasOwnProperty: ƒ hasOwnProperty()isPrototypeOf: ƒ isPrototypeOf()propertyIsEnumerable: ƒ propertyIsEnumerable()toLocaleString: ƒ toLocaleString()toString: ƒ toString()arguments: (...)caller: (...)length: 0name: "toString"__proto__: ƒ ()Scopes: Scopes[0]valueOf: ƒ valueOf()__defineGetter__: ƒ __defineGetter__()__defineSetter__: ƒ __defineSetter__()__lookupGetter__: ƒ __lookupGetter__()__lookupSetter__: ƒ __lookupSetter__()get __proto__: ƒ __proto__()set __proto__: ƒ __proto__() ``` * So this returns an Object, but in gf-repeater.min.js, I see this : `gfRepeater_repeaters[ e][r]` Where e represents the first parameter passed to gfRepeater_repeatRepeater() and r represents the second one. So my guess is that this is an Object ( gfRepeater_repeater) and when we try to access gfRepeater_repeaters[e][r], it returns undefined. * Knowing that, I still have no clue on how to work around this! * If you have any idea on this please reply. - This reply was modified 8 years, 3 months ago by [jimmysurprenant](https://wordpress.org/support/users/jimmysurprenant/). * Thread Starter [cramaekers](https://wordpress.org/support/users/cramaekers/) * (@cramaekers) * [8 years, 3 months ago](https://wordpress.org/support/topic/solved-javascript-error/#post-9906073) * I ended up just installing the latest version from the [project’s GitHub page](https://github.com/kodie/gravityforms-repeater) and all is well on my end.

I’ve inspected element and see that there are no onClick action on the buttons. * It does work on preview mode on the form, but still not working when I put this on the website! * That is a strange behaviour! * Thread Starter [cramaekers](https://wordpress.org/support/users/cramaekers/) * (@cramaekers) * [8 years, 3 months ago](https://wordpress.org/support/topic/solved-javascript-error/#post-9906284) * If the preview works I would assume this is an error within your theme. What theme are you using? Have you tried reverting back to a default theme, like Twenty Seventeen? * [jimmysurprenant](https://wordpress.org/support/users/jimmysurprenant/) * (@jimmysurprenant) * [8 years, 3 months ago](https://wordpress.org/support/topic/solved-javascript-error/#post-9906314) * This is a custom theme, all the default themes have been deleted (I don’t know why, I have not developed this theme myself) Also, I have FTP access and cPanel, I do not have access to staging environment so it is complicated to try changing theme as it will affect the display. * If you don’t mind, I could maybe create an editor account for you so you can take a look to see what really happen? * Thread Starter [cramaekers](https://wordpress.org/support/users/cramaekers/) * (@cramaekers) * [8 years, 3 months ago](https://wordpress.org/support/topic/solved-javascript-error/#post-9906324) * Sorry, I don’t have time currently to delve into a custom theme. I’d recommend creating a staging site so you can test, or put up a temporary “Down For Maintenance” message for 1 minute while you swap themes and check. That’s the only way to know for sure where you problem is. * [jimmysurprenant](https://wordpress.org/support/users/jimmysurprenant/) * (@jimmysurprenant) * [8 years, 3 months ago](https://wordpress.org/support/topic/solved-javascript-error/#post-9906358) * Ok no problem, thank you very much for the hints, I will try that out and come up with the results! * Thread Starter [cramaekers](https://wordpress.org/support/users/cramaekers/) * (@cramaekers) * [8 years, 3 months ago](https://wordpress.org/support/topic/solved-javascript-error/#post-9906362) * Happy to try and help.

Then when the JS tries to parse it, it’s completely unexpected, and ruins our day. * For me the fix came around line 222, just beneath the list of the variable declarations, just add a simple check to make sure ‘childInfo’ is defined. * if (childInfo === undefined) { return false; } Viewing 11 replies - 1 through 11 (of 11 total) The topic ‘Solved Javascript error’ is closed to new replies. * ![](https://s.w.org/plugins/geopattern-icon/repeater-add-on-for-gravity-forms_f9f9f9. svg) * [Gravity Forms Repeater Add-On](https://wordpress.org/plugins/repeater-add-on-for-gravity-forms/) * [Frequently Asked Questions](https://wordpress.org/plugins/repeater-add-on-for-gravity-forms/#faq) * [Support Threads](https://wordpress.org/support/plugin/repeater-add-on-for-gravity-forms/) * [Active Topics](https://wordpress.org/support/plugin/repeater-add-on-for-gravity-forms/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/repeater-add-on-for-gravity-forms/unresolved/) * [Reviews](https://wordpress.org/support/plugin/repeater-add-on-for-gravity-forms/reviews/) * 11 replies * 3 participants * Last reply from: [devinswett](https://wordpress.org/support/users/devinswett/) * Last activity: [8 years, 3 months ago](https://wordpress.org/support/topic/solved-javascript-error/#post-9967224) * Status: not a support question
