Topic: Foreach error with mdb-auto-completer

itay pro asked 4 years ago


I am getting a lot of errors of: TypeError: Object doesn't support property or method 'forEach'

Although I don't seem to find exactly the source, nor reproduce it, it does looks as if it originates from within the implementation of mdb-auto-completer, perhaps with option list is empty

Here is a snippet of production code: n.prototype.show=function(){this._isOpen=!0},n.prototype.hide=function(){this._isOpen=!1},n.prototype.removeHighlight=function(n){var e=this;setTimeout(function(){e.optionList.forEach(function(t,l){var i=t.nativeElement.querySelectorAll(".completer-row");l===n?e.renderer.addClass(t.nativeElement.firstElementChild,"highlight-row"):l!==n&&i.forEach(function(n){e.renderer.removeClass(n,"highlight-row")})})},0)},n.prototype.highlightRow=function(n){var e=this;this._allItems=this.optionList.filter(function(n){return n.nativeElement.firstElementChild.classList.contains("completer-row")}).map(function(n){return n.nativeElement}),this._allItems[n]&&this.optionList.forEach(function(t,l){var i=t.nativeElement.querySelectorAll(".completer-row");n===l&&(e.removeHighlight(n),e.renderer.addClass(i[i.length-1],"highlight-row"))}),this._selectedItemIndex=n}

The source is the foreach in here: ... (t.nativeElement.firstElementChild,"highlight-row"):l!==n&&i.forEach(function(n){e.renderer.removeClass(n,"highlight-row")})})},0)},n.protot ...

Are you familiar with this and can guide me to a solution ?

Do you recognize the code snippet ?

This is the information I get from the users: User-Agent = Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko Some use chrome, some edge

Dear mdb2,

We didn't discover any errors while using or building the MDB Pro library.

Without guideline how to reproduce this problem I won't be able to help you, because, on my side, there are no errors in the whole MDB Angular library. Especially with .forEach() method.

On which browser you're getting those errors? Also provide me the full environment informations - OS, Device, Angular version, Node version.

Best Regards,

Damian
