Adobe Illustrator 删除了我在 svg 图像上的 class 个名字。我怎样才能防止这种情况发生？
Adobe Illustratore delete my class names on svg images. How can I prevent this?

不幸的是，每次编辑后 rewrite/save 您的 svg 时，AI 都会删除您的自定义 classes。
我使用 2 个辅助函数想出了这个（诚然相当笨拙）的解决方法：
- svgClass2ID(svg)：将自定义 class 名称转换为 ID。在 AI 中打开文件时将保留 ID。
- aiID2Class(svg)：通过将 AI 层 ID 转换为 class 名称来恢复您的 classes。您可以“存储”多个 classes.
这样您就可以通过编辑图层 ID 在 AI 中设置 classes。
多个 class 名称是使用“--”（2 个连字符）作为分隔符创建的。
示例 1：prepare/optimize 你的 AI svg
自定义 classes 将被转换为 ID – 检查控制台是否有新的 svg 标记。
const svgWeb = document.querySelector('#svgWeb');
svgClass2ID(svgWeb);
/**
* svg classes to AI layer IDs:
* run this once to store classnames in layer IDs before reediting in AI
*/
function svgClass2ID(svg) {
let elements = [...svg.children];
let svgClass = svg.getAttribute('class');
let svgID = svg.id ? svg.id : svgClass.split(' ').join('--');
let allIDs = [];
let processed = 0;
if (svgID) {
svg.id = svgID;
}
if (elements.length) {
elements.forEach(function (el, i) {
let id = el.id;
let className = el.getAttribute('class');
let classList = className ? className.split(' ') : [];
let newID = classList.join('--');
if (allIDs.indexOf(newID) == -1) {
allIDs.push(newID)
} else {
if(!id ){
console.log('id "' + newID + '" is not unique.');
// add index number to make id unique
classList[0] = classList[0] + '-' + i + '--' + classList[0];
newID = classList.join('--');
}
}
// save classes in id attribute
if (!id) {
el.id = newID;
processed++;
}
})
if(processed){
let svgMarkup = svg.outerHTML;
console.log(svgMarkup)
}
}
}

因此，如果您只需要将 'id' 替换为 'class' 并返回，则可以使用 Extendscript 轻松完成。
第一个脚本打开您的 svg 文件，将 'class' 替换为 'id'，添加文件名“_id”并将新的 svg 文件保存到同一文件夹中：
var file = File.openDialog();
if (file) {
file.open('r');
var contents = file.read();
file.close();
contents = contents.replace(/class="/g, 'id="');
var new_file_name = file.fullName.replace(/\.svg$/, '_id.svg');
var new_file = File(new_file_name);
new_file.open('w');
new_file.write(contents);
new_file.close();
}
第二个脚本反之亦然：将 'id' 替换为 'class'，将“_class”添加到文件名并将文件保存到同一文件夹中。
var file = File.openDialog();
if (file) {
file.open('r');
var contents = file.read();
file.close();
contents = contents.replace(/id="/g, 'class="');
var new_file_name = file.fullName.replace(/(_id\.svg|\.svg)$/, '_class.svg');
var new_file = File(new_file_name);
new_file.open('w');
new_file.write(contents);
new_file.close();
}
如果您足够勇敢，可以将更新后的内容保存到同一个 svg 文件中，无需备份，如下所示：
var file = File.openDialog();
if (file) {
file.open('r');
var contents = file.read();
file.close();
contents = contents.replace(/class="/g, 'id="');
// or
// contents = contents.replace(/id="/g, 'class="');
file.open('w');
file.write(contents);
file.close();
}

不幸的是，每次编辑后 rewrite/save 您的 svg 时，AI 都会删除您的自定义 classes。
我使用 2 个辅助函数想出了这个（诚然相当笨拙）的解决方法：
- svgClass2ID(svg)：将自定义 class 名称转换为 ID。在 AI 中打开文件时将保留 ID。
- aiID2Class(svg)：通过将 AI 层 ID 转换为 class 名称来恢复您的 classes。您可以“存储”多个 classes.
这样您就可以通过编辑图层 ID 在 AI 中设置 classes。
多个 class 名称是使用“--”（2 个连字符）作为分隔符创建的。
示例 1：prepare/optimize 你的 AI svg
自定义 classes 将被转换为 ID – 检查控制台是否有新的 svg 标记。
const svgWeb = document.querySelector('#svgWeb');
svgClass2ID(svgWeb);
/**
* svg classes to AI layer IDs:
* run this once to store classnames in layer IDs before reediting in AI
*/
function svgClass2ID(svg) {
let elements = [...svg.children];
let svgClass = svg.getAttribute('class');
let svgID = svg.id ? svg.id : svgClass.split(' ').join('--');
let allIDs = [];
let processed = 0;
if (svgID) {
svg.id = svgID;
}
if (elements.length) {
elements.forEach(function (el, i) {
let id = el.id;
let className = el.getAttribute('class');
let classList = className ? className.split(' ') : [];
let newID = classList.join('--');
if (allIDs.indexOf(newID) == -1) {
allIDs.push(newID)
} else {
if(!id ){
console.log('id "' + newID + '" is not unique.');
// add index number to make id unique
classList[0] = classList[0] + '-' + i + '--' + classList[0];
newID = classList.join('--');
}
}
// save classes in id attribute
if (!id) {
el.id = newID;
processed++;
}
})
if(processed){
let svgMarkup = svg.outerHTML;
console.log(svgMarkup)
}
}
}

因此，如果您只需要将 'id' 替换为 'class' 并返回，则可以使用 Extendscript 轻松完成。
第一个脚本打开您的 svg 文件，将 'class' 替换为 'id'，添加文件名“_id”并将新的 svg 文件保存到同一文件夹中：
var file = File.openDialog();
if (file) {
file.open('r');
var contents = file.read();
file.close();
contents = contents.replace(/class="/g, 'id="');
var new_file_name = file.fullName.replace(/\.svg$/, '_id.svg');
var new_file = File(new_file_name);
new_file.open('w');
new_file.write(contents);
new_file.close();
}
第二个脚本反之亦然：将 'id' 替换为 'class'，将“_class”添加到文件名并将文件保存到同一文件夹中。
var file = File.openDialog();
if (file) {
file.open('r');
var contents = file.read();
file.close();
contents = contents.replace(/id="/g, 'class="');
var new_file_name = file.fullName.replace(/(_id\.svg|\.svg)$/, '_class.svg');
var new_file = File(new_file_name);
new_file.open('w');
new_file.write(contents);
new_file.close();
}
如果您足够勇敢，可以将更新后的内容保存到同一个 svg 文件中，无需备份，如下所示：
var file = File.openDialog();
if (file) {
file.open('r');
var contents = file.read();
file.close();
contents = contents.replace(/class="/g, 'id="');
// or
// contents = contents.replace(/id="/g, 'class="');
file.open('w');
file.write(contents);
file.close();
}
