2、修改functions.php

路径 /Joe/functions.php

代码 // 评论图片 $CommentImg = new Typecho_Widget_Helper_Form_Element_Select(

'CommentImg',
array('on' =>
     '开启（默认）', 'off' =>
     '关闭'),
'on',
'是否开启评论图片功能',
'介绍：开启后，评论区域可以选择图片进行评论'

); CommentImg-> setAttribute('class', 'joe_content joe_custom');

3、新增custom.js

路径 Joe/assets/js/custom.js

// 评论图片功能
$(".imgUpload #imgUpload_btn_upload").click(function() {
    
    $(".imgUpload #imgUpload_btn_file").click();

}
    );


$(".imgUpload #imgUpload_btn_clear").click(function() {
    
    $(".imgUpload #imgUpload_img").attr('src', '');
    
    $(".imgUpload #imgUpload_img").hide();
    
    $('.joe_comment__respond-form .body .text').show();
    
    $(".imgUpload #imgUpload_btn_file").val('');
    
    $(".joe_comment__respond-form .body textarea[name='text']").val('');

}
    );


$(".imgUpload #imgUpload_btn_file").change(function() {
    
    var gs = this.files[0].name.split(".").pop().toLowerCase();
    
    if (gs!="jpg" &
    &
     gs!="png" &
    &
 gs!="gif") {
    
        alert("请上传.jpg，.png，.gif格式文件");
     
        return false;

    }
    
    //预览图片编码并显示
    var reader = new FileReader();

    reader.onloadend = function(e) {

        dealImage(e.target.result, 200, function(compressImg) {
    
            $(".imgUpload #imgUpload_img").attr('src', compressImg);

            $(".joe_comment__respond-form .body textarea[name='text']").val('{
!{
' + compressImg + '}
!}
     ');
    
            $(".imgUpload #imgUpload_img").show();
    
            $('.joe_comment__respond-form .body .text').hide();

        }
    );

    }
    
    reader.readAsDataURL(this.files[0]);

}
    );



/**
 * 压缩图片 
 */
function dealImage(base64, w, callback) {
    
    var newImage = new Image()
    //压缩系数0-1之间
    var quality = 0.6;
    
    newImage.src = base64;
    
    newImage.setAttribute('crossOrigin', 'Anonymous');
        //url为外域时需要
    var imgWidth, imgHeight;
    
    var ba = null;

    newImage.onload = function () {
    
        imgWidth = this.width;
    
        imgHeight = this.height;
    
        var canvas = document.createElement('canvas');
    
        var ctx = canvas.getContext('2d');
    
        if (Math.max(imgWidth, imgHeight) >
 w) {
    
            if (imgWidth >
 imgHeight) {
    
                canvas.width = w;
    
                canvas.height = w * imgHeight / imgWidth;

            }
 else {
    
                canvas.height = w;
    
                canvas.width = w * imgWidth / imgHeight;

            }

        }
 else {
    
            canvas.width = imgWidth;
    
            canvas.height = imgHeight;
    
            quality = 0.6;

        }
    
        ctx.clearRect(0, 0, canvas.width, canvas.height);
    
        ctx.drawImage(this, 0, 0, canvas.width, canvas.height);
    
        // 如想确保图片压缩到自己想要的尺寸,如要求在50-150kb之间，请加以下语句，quality初始值根据情况自定
        while (base64.length / 1024 >
 30) {
    
            quality -= 0.01;
    
            base64 = canvas.toDataURL("image/jpeg", quality);

        }

        // 防止最后一次压缩低于最低尺寸，只要quality递减合理，无需考虑
        while (base64.length / 1024  20) {
    
            quality += 0.001;
    
            base64 = canvas.toDataURL("image/jpeg", quality);

        }
    
        var ba = canvas.toDataURL('image/jpeg', quality);
     //压缩语句
        callback(ba);

    }

}
    

4、修改joe.global.js，

路径 /Joe/assets/js/joe.global.js ，将原先的单词换成这个text，然后用vs code压缩js生成joe.global.min.js
