在现有的javascript函数中插入一些jquery代码

Question

Working with some code, i had modified some code where i am doing some manipulation of selections, but i need to insert some code after the specific javascript code:

The code is

product.options[product.options.length] = newoption;
    switch(cSelected) {

i want it to be:

product.options[product.options.length] = newoption;
        var x = 0;
        while(x < cSelected.length){
            switch(cSelected[x]) {

now the identification line is:

product.options[product.options.length] = newoption;

i am trying to use insertAfter but lost how to add this

same case is the ending of the function

break;

    }

}

need to be like this:

break;

            }
            x++;
        }

    }

If you have access to the source file you should make the changes directly. If not you can replace the reference with your own function declaration so that any subsequent calls to the function will execute your function. Note that any bounded references to the original function will not be overridden and will still call the original function.

//original
function llama() {
    product.options[product.options.length] = newoption;
    switch(cSelected) {}
}
//your new function
llama = function(){
product.options[product.options.length] = newoption;
var x = 0;
while(x < cSelected.length){
    switch(cSelected[x]) {}
x++;
}
}
