期望一个赋值或函数调用，而是看到一个表达式

Question

I am using JSLint to ensure my JavaScript is "strict" and I'm getting the following error: Expected an assignment or function call and instead saw an expression

On the following code: if(index>0){ shakStaute===1; } if(index>0){ shakStaute===1; }

Answer 1

JSLint is flagging up that shakSuite===1; is a pointless statement. The only thing it does is evaluate the variable shakSuite , compare its value with 1 , and then throw away the result of the comparison. It doesn't do anything else.

If your goal is to set shakSuite to the value 1 , you want = (assignment), not === (strict equality comparison):

if (index > 0) {
    shakSuite = 1;
}
