Uncaught SyntaxError: Unerwartetes Token - Fehler in einigen Browsern

Question

Ich habe ein Problem mit folgenden Codes. Es gibt kein Problem mit Chrome, Firefox und Opera. Aber es zeigt nichts auf Maxthon Browser, einige mobile und TV-Browser. Ich habe diesen Fehler in der Konsole von Maxthon Browser: Uncaught Syntaxerror: Unexpected token =

Meine Codes sind hier:

        <div class="SerieSeaons"> 
            <div class="seasons-link filters-button-group"> 
             <?php $s= 1; foreach ($seasons as $season) { 
              ?> 
              <a class="seasonlink <?php if($s == 1) { echo 'active'; } else { echo 'notloaded'; }?>" href="JavaScript:void(0);" 
               data-filter=".<?php echo $season->slug; ?>"><?php echo $season->name; ?></a> 
              <?php $s++; } ?> 
            </div> 
            <div class="el-item title sort-by-button-group button-group"> 
             <div class="sortitem status" data-sort-value="status">Watched</div> 
             <div class="season-name">Season</div> 
             <div class="sortitem episode-name hidden-xs" data-sort-value="episodename">Episode</div> 
             <div class="sortitem e-name" data-sort-value="ename">Episode Name</div> 
             <div class="sortitem date hidden-xs" data-sort-value="date">Air Date</div> 
            </div> 
            <div class="psscroll" style="height:100%"> 
             <div class="all-seriespart"> 
              <div class="asisotope" id="rp_<?php echo esc_attr($rp_id); ?>"></div>

Answer 1

Sie verwenden ES6 default function parameters, etwas, das nur sehr aktuelle Browser unterstützen.

Entweder Sie verwenden diese Sprachfeatures nicht oder richten einen Code wie Babel ein, um den Code in kompatiblen Code zu übertragen.

Dies ist der Code mit Standardparametern

function multiply(a, b = 1) { 
    return a * b; 
} 

dies in älteren Browsern als auch

function multiply(a, b) { 
    b = (typeof b !== 'undefined') ? b : 1; 
    return a * b; 
}
