Question

I am trying to pass a string value to a basic javascript function and get the following error

Uncaught syntax error:unexpected token illegal

This is the code behind

string value = "7dim-034/hallo/01:22"
<input type = 'button' value='submit' id='butSimulate' onClick='saveViewItemTester("+value+")'

and this is the function This is the javascript

function saveViewItemTester(prod) {
    alert(prod);
}

Help with resolving this little issue if possible

kind regards

Answer 1

There are several issues:

• no types in javascript
• value is reserved word, don't use it as variable name
• input tag isn't closed
• no need to "+" the variable
• use ; in javascript

Use this in between the head tags:

<script type="text/javascript">
var test = "7dim-034/hallo/01:22";

function saveViewItemTester(prod) {
  alert(prod);
}
</script>

Use this between the body tags:

<input type="button" value="submit" id="butSimulate" onClick="saveViewItemTester(test)" />

Answer 2

Javascript is a typeless language. If you want a string, just assign it:

 value = "7dim-034/hallo/01:22";

Answer 3

Try this, in case value is C# code

 <input type = 'button' value='submit' id='butSimulate' 
        onClick='saveViewItemTester('<%=value%>')'/>

else use as

   var value = "7dim-034/hallo/01:22";
   <input type = 'button' value='submit' id='butSimulate' 
        onClick='saveViewItemTester('+ value +')'/>

Answer 4

只需在函数调用中将"转换为' ，即可：

<input type = 'button' value='submit' id='butSimulate' onClick='saveViewItemTester('+value+')'/>

Answer 5

for C#, string value = "7dim-034/hallo/01:22"

<input type = 'button' value='submit' id='butSimulate' 
    onClick='saveViewItemTester("<%=value%>")'/>

Answer 6

这应该工作

<input type="button" value="submit" id="butSimulate" onclick="saveViewItemTester('7dim-034/hallo/01:22')" />

Answer 7

Re-factor your code as follows-

C# code-

 public string value = "7dim-034/hallo/01:22";

Javascript Code-

<input type = 'button' value='submit' id='butSimulate' onclick='saveViewItemTester("<%=value%>")'/>

function saveViewItemTester(prod) {
    alert(prod);
}

Answer 8

maybe you can pass the value without "+" and declaring without String, just var. for example:

var value = "hola";

<input type="button" value="submit" id="butSimulate" onclick="saveViewItemTester(value)"/>
