When I opened the Blizzard Launcher today after work I saw the following rather than the usual Images/ads:
var BlzPassword = function($input, options) { if (!$input) { return; } if (window.DOMTokenList && !window.DOMTokenList.prototype.forEach) { window.DOMTokenList.prototype.forEach = function (callback, thisArg) { thisArg = thisArg || window; for (var i = 0; i < this.length; i++) { callback.call(thisArg, this[i], i, this); } }; } if (document.msCapsLockWarningOff === false) { document.msCapsLockWarningOff = true; } this.visibilityToggle = options ? options.visibilityToggle : true; this.strengthIndicator = options ? options.strengthIndicator : false; this.passwordStrengthValues = this.strengthIndicator ? options.strengthValues : []; this.passwordStrengthText = this.strengthIndicator ? options.strengthText : ""; this.passwordStrengthDefaultLabel = this.strengthIndicator ? options.strengthDefaultText : ""; this.capsLockOn = false; this.showPassword = false; this.passwordStrengthValue = 0; var wrapper = document.createElement("div"); wrapper.classList.add("blz-password-wrapper"); $input.parentNode.insertBefore(wrapper, $input); wrapper.appendChild($input); var capsLockSpan = document.createElement("span"); capsLockSpan.classList.add("caps-lock-indicator"); capsLockSpan.classList.add("hide"); var capsLockIcon = document.createElement("i"); capsLockIcon.classList.add("fas"); capsLockIcon.classList.add("fa-arrow-alt-square-up"); capsLockSpan.appendChild(capsLockIcon); if (this.visibilityToggle) { var viewPasswordButton = document.createElement("span"); viewPasswordButton.classList.add("view-password-button"); var viewPasswordIcon = document.createElement("i"); viewPasswordIcon.classList.add("show-password"); viewPasswordIcon.classList.add("fas"); viewPasswordIcon.classList.add("fa-eye"); var hidePasswordIcon = document.createElement("i"); hidePasswordIcon.classList.add("hide-password"); hidePasswordIcon.classList.add("hide"); hidePasswordIcon.classList.add("fas"); hidePasswordIcon.classList.add("fa-eye-slash"); viewPasswordButton.appendChild(viewPasswordIcon); viewPasswordButton.appendChild(hidePasswordIcon); wrapper.appendChild(viewPasswordButton); } wrapper.appendChild(capsLockSpan); this.$blzPassword = wrapper; }; BlzPassword.prototype = { init: function() { if (!this.$blzPassword) { return; } var input = this.$blzPassword.querySelector("input"); input.addEventListener("keydown", this.capsLockListener.bind(this)); input.addEventListener("keyup", this.capsLockListener.bind(this)); input.addEventListener("click", this.capsLockListener.bind(this)); input.addEventListener("focus", this.capsLockListener.bind(this)); input.addEventListener("blur", this.clearIndicators.bind(this)); var viewPasswordButton = this.$blzPassword.querySelector(".view-password-button"); viewPasswordButton.addEventListener("click", this.togglePassword.bind(this)); if (this.strengthIndicator === true) { this.createStrengthIndicator(); } }, createStrengthIndicator: function() { var progressBar = document.createElement("progress"); progressBar.classList.add("password-strength-meter"); progressBar.setAttribute("max", "100"); progressBar.setAttribute("value", "0"); var strengthLabel = document.createElement("div"); strengthLabel.classList.add("password-strength-status"); this.$blzPassword.appendChild(progressBar); this.$blzPassword.appendChild(strengthLabel); this.setPasswordStrengthText(this.passwordStrengthDefaultLabel); }, capsLockListener: function(e) { if (e.type === "focus") { e.target.click(); return; } if (e.getModifierState("CapsLock")) { if (!this.capsLockOn) { this.setCapsLock(true); } } else if (this.capsLockOn) { this.setCapsLock(false); } }, setCapsLock: function(value) { var capsLockIndicator = this.$blzPassword.querySelector(".caps-lock-indicator"); if (value === true) { capsLockIndicator.classList.remove("hide"); } else { capsLockIndicator.classList.add("hide"); } this.capsLockOn = value; }, togglePassword: function() { if (this.showPassword === true) { this.displayPassword(false); } else { this.displayPassword(true); } }, displayPassword: function(value) { if (value === true) { this.$blzPassword.querySelector("input").setAttribute("type", "text"); this.$blzPassword.querySelector(".show-password").classList.add("hide"); this.$blzPassword.querySelector(".hide-password").classList.remove("hide"); } else { this.$blzPassword.querySelector("input").setAttribute("type", "password"); this.$blzPassword.querySelector(".hide-password").classList.add("hide"); this.$blzPassword.querySelector(".show-password").classList.remove("hide"); } this.showPassword = value; }, clearIndicators: function(e) { if (!e.target.classList.contains("view-password-button") && !e.target.classList.contains("caps-lock-indicator")
As a software engineer I think It’s pretty safe to say that this was unintentional, and I felt I should let someone know that some of your front-end code is exposed.
Also your code isn’t fully minimized and that increases the file size. I recommend using one of the many available open-source tools to accomplish this.
