Question

I have a ACF text field.

I want to use the previous post on these texts, but my code doesn't work...

This is this line that doesn't work :

var r = parseInt('<?php the_field('red', $prev_post->ID); ?

Here's my code :

 $(document).ready(function() {

    $(".next_image_cover a").hover(

        function() {

        var r = parseInt('<?php the_field('red', $prev_post->ID); ?>'); 
        var g = parseInt('<?php the_field('green', $prev_post->ID); ?>'); 
        var b = parseInt('<?php the_field('blue', $prev_post->ID); ?>'); 


        $("body").stop().animate({"background-color": "rgb(" + r + "," + g + "," + b + ")"}, "200");
        },
        function() {

        $("body").stop().animate({"background-color": "#e6e6e6"}, "200");

    });

您不能在JavaScript中使用php变量-

parseInt('<?php the_field('red'); ?>', **$prev_post->ID**);
