下面是一个完整的代码示例,演示了如何将字符串转换为 Blob 对象,并将其保存为文件。 functionstringToBlob(str){letarray=[str];letblob=newBlob(array,{type:'text/plain'});returnblob;}functionsaveBlobToFile(blob,filename){letlink=document.cr
var lcString = myString.toLowerCase(); //结果: "hello" var ucString = myString.toUpperCase(); //结果: "HELLO" 5.字符串比较 var aString = "Hello!"; var bString = new String("Hello!"); if( aString == "Hello!" ){ } //结果: true if( aString == bString ){ } //结果: tr...
