Normally, the passing parameters are about this:

Copy code code as follows:

var numparameter = 123;

Function Sendparameter ()

{{

getparameter (numparameter);

}

Function GetParameter (Sendnum)

{{

alert (sendnum);

}

Very simple A method call method B and pass on.

However, if the parameters of the B method are not fixed, it may be based on different situations, which require different parameters, and can be written like this:

Copy code code as follows:

var txtParameter1 = "123";

var txtParameter2 = "234";

var txtParameter3 = "345";

var txtsendparameter = "";

var flag = 0;

Function Sendparameter1 ()

{{

Flag = 1;

txtsendparameter = txtParameter1 + ";" + txtParameter2;

getparameter ();

}

Function Sendparameter2 ()

{{

Flag = 2;

txtsendparameter = txtParameter2 + ";" + txtParameter3;

getparameter ();

}

Function getparameter ()

{{

if (1 == Flag)

{{

// GOTO FUNCTIONC (TXTSENDPARAMETER)

}

else if (2 == Flag)

{{

// GOTO FUNCTIND (TXTSENDPARAMETER)

}

else

{{

Return;

}

Can you use global variables to pass the value:

Copy code code as follows:

var txtParameter1 = "123";

var txtParameter2 = "234";

var txtParameter3 = "345";

Function Sendparameter1 ()

{{

var txtsendparameter = "1" + txtParameter1 + ";" + txtParameter2;

getparameter (txtSendparameter);

}

Function Sendparameter2 ()

{{

var txtsendparameter = "2" + txtParameter2 + ";" + txtParameter3;

getparameter (txtSendparameter);

}

Function getparameter ()

{{

switch (Arguments [0])

{{

case "1":

// Goto functionc (arguments);

Break;

case "2":

// Goto functions (arguments);

Break;

DEFAULT:

// GOTO FUNCTIONE (ARGUMENTS);

}

Relatively speaking, arguments are a very flexible object. Although it is not array, it can use the lower bidding value as array. Although it is a bit remote, it is still very easy to use.

Copy code code as follows:
