This is my code, anyone can help me Click the function on the onclick function insert1 ( ); Calling is not calling when clicking on Calling button If I use the script in the head part, then it also does not work. 

  & lt; Html & gt; & Lt; Top & gt; & Lt ;? Php $ mode = ""; $ SNO = ""; $ Name = ""; $ Gender = ""; $ Age = ""; If (isset ($ _ request ["mode"])) $ mode = $ _ request ["mode"]; And $ mode = "list"; If ($ mode == "save") {$ sno = $ _ request ['sno']; $ Name = $ _ request ['name']; $ Gender = $ _ request ['gender']; $ Age = $ _ request ['age']; $ Con = mysqli_connect ("localhost", "root", "", "outpost"); Insert $ Sql ​​= "atom (name, gender, age) value ('$ name', '$ gender', '$ age')"; Mysqli_query ($ thief, $ sql); }? & Gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt ;? Php if ($ mode == "LIST") {? & Gt; & Lt; Center & gt; & Lt; Pre & gt; Sno & lt; Input type = "text" name = sno id = sno readonly & gt; & Lt; Br> Name & lt; Input type = text name = name id = name & gt; & Lt; Br> Gender & lt; Input type = text name = gender id = gender & gt; & Lt; Br> Age & lt; Input type = text name = age id = age & gt; & Lt; Br> & Lt; Input type = button onclick = "insert1 ();" Value = insert & gt; & Lt; Br> & Lt; Input type = "button" onClick = "fnsave ();" Class = "button" value = "save" & gt; & Lt; / Center & gt; & Lt ;? Php}? & Gt; & Lt; Script & gt; Function insert1 () {warning ("t"); Var sno = document.getElementById ("snow"). Values; Var name = document.getElementById ("name"). Values; Var gender = document.getElementById ("gender"). Values; Var Age = Document. GetElementById ("Age"). value; Window.location = "file3.php? Sno =" + sno + "& amp; name =" + name + "& gender =" + gender + "age =" + + + age + "and mode =" save " ;}  & lt; / body & gt;

Your error javascript, this is the reason why this method is not working. 

  window.location = "file3.php? Sno = "+ sno +" & amp; Name = "+ name +" & amp; Gender = "+ gender +" age = "+ age +" & amp; Mode = "save";

should see 

  "and mode =" save ";

should be:

"& amp; Apart from this, @ Bhav has found another error in your Vars, it does not work from JS, but creates an incorrect URL.

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
