// svg 转成url

		.replace(/<!--(.*)-->/g, "")
		.replace(/[\r\n]/g, " ")
		.replace(/"/g, `'`)
		.replace(/%/g, "%25")

		.replace(/#/g, "%23")
		.replace(/{/g, "%7B")
		.replace(/}/g, "%7D")
		.replace(/</g, "%3C")
		.replace(/>/g, "%3E");

	let res = '"' + `data:image/svg+xml,${encoded}` + '"'; //需要在字符串前后加上一对引号（非常关键！）
	return res;
}

// svg 修改图片颜色
export function svgChangeColor(url: any, color: string) {
	let modifiedStr;
	// 全颜色修改
	modifiedStr = url.replace(/%23[a-zA-Z0-9]{6}/g, color.replace("#",
		"%23")); //转义后的#等于%23，利用正则表达式，替换所有%23后6位为新的十六进制六位数。
