推荐答案

尝试下面code：

protected void Page_Load(object sender, EventArgs e)
{
    System.Web.UI.ScriptManager.RegisterStartupScript(this, this.GetType(), "abc", "abc();", true);
}

1。更新>传递字符串参数：

protected void Page_Load(object sender, EventArgs e)
{
    var message = "hi";
    System.Web.UI.ScriptManager.RegisterStartupScript(this, this.GetType(), "abc", "abc('" + message + "');", true);
}

JavaScript方法用字符串参数：

JavaScript Method with string parameter :

function abc(message) {
    alert(message + ", I am an alert box!");
}

2。更新>传递字符串参数和数值数组JS方法：

protected void Page_Load(object sender, EventArgs e)
{
    int[] numbers = { 10, 20, 30 };

    string serializedNumbers = (new JavaScriptSerializer()).Serialize(numbers);

    var message = "hi";
    System.Web.UI.ScriptManager.RegisterStartupScript(this, this.GetType(), "abc", "abc('" + message + "', " + serializedNumbers + ");", true);
}

用绳子和数​​值数组参数JavaScript方法：

JavaScript Method with string and numeric array parameters:

function abc(message, numbers) {

    alert(message + ", I am an alert box!");
    for (var i = 0; i < numbers.length; i++) {
        alert(numbers[i]);
    }
}
