我需要访问匿名绑定函数之外的jqconsole变量。我如何在 JQuery 栖息地之外实例化它？如果可能的话，我会把它保存在全局或我的州。我没有设法让它以这种方式运行。
componentDidMount = () => {
// Execute after fully loaded
$(window).bind('load', () => {
const jqconsole = $('#console').jqconsole(
'Welcome to the console!\n',
'>'
);
// register some workarounds
jqconsole.RegisterMatching('{', '}', 'brace');
jqconsole.RegisterMatching('(', ')', 'paran');
jqconsole.RegisterMatching('[', ']', 'bracket');
const startPrompt = () => {
// scroll to bottom -- NOT WORKING YET
$('#console').scrollTop($('#console')[0].scrollHeight);
// Start the prompt with history enabled.
jqconsole.Prompt(true, input => {
let transformedString;
// Manage Output
try {
transformedString = window.eval(input);
if (typeof transformedString === 'object') {
this.writeToConsole(jqconsole, 'object', transformedString);
} else {
this.writeToConsole(jqconsole, 'message', transformedString);
}
// Restart the input prompt.
startPrompt();
} catch (error) {
this.writeToConsole(jqconsole, 'error', error);
// Restart the input prompt.
startPrompt();
}
});
};
// Restart the input prompt.
startPrompt();
});
};
准确地说：我有这个类方法writeToConsole，并且想调用它而不必传递 jqconsole 的实例：
// Manage Output
writeToConsole = (jqconsole, type, message) => {
console.log('writing to console @ console');
if (type === 'error') {
jqconsole.Write(message + '\n', 'jqconsole-output-error');
} else if (type === 'message') {
jqconsole.Write(message + '\n', 'jqconsole-output');
} else if (type === 'object') {
jqconsole.Write(JSON.stringify(message) + '\n', 'jqconsole-output');
} else {
console.log('error @ writeToConsole');
return null;
}
};
感谢您的时间和帮助。
