In this example, we define a function called "custom_function" that takes a parameter 'x' and calculates a quadratic expression. We then create a string variable called "expression" containing the function call with the argument '3'. To evaluate the expression, we use the eval() function, ...

function myFunc() { var i = 'test'; window.eval('i="hello."'); } myFunc(); alert(i); 然后不幸的是:在IE下不管是window.eval()还是eval()方法输出的都是100;但是在标准浏览器下使用window.eval(),输出的是hello,使用eval()方法的输出的是100; 因为IE下使用的是JScript引擎的,而标准浏览器下是...
Example 1: How eval() works in Python x =1 print(eval('x + 1')) Run Code Output 2 Here, theeval()function evaluates the expressionx + 1andprint()is used to display this value. Example 2: Practical Example to Demonstrate Use of eval() ...
