將TextBox.Value傳遞給模態表單Label.Text OnClick

Question

當單擊圖像時，我想以模態形式捕獲圖像上的光標坐標，但我很喜歡JavaScript。 我也希望僅在單擊圖像時才打開模式窗體。 當用戶單擊窗口中的任意位置時，當前會彈出模式窗體。 凡是可以幫助我在窗口中居中顯示模式表格的人，都將獲得獎金標記！

任何見解將不勝感激。

這是我到目前為止有：

的HTML

<a onmouseover="document.body.style.cursor='crossHair'" 
    onmouseout="document.body.style.cursor='default'" 
    onmousemove="getXY(event)">
    <img id="Image" src="../Images/TestImage.jpg" alt=""/></a><br/><br/>

X = <input type="text" id="xVal" size="1" readonly="true"/> &nbsp;
Y = <input type="text" id="yVal" size="1" readonly="true"/><br/><br/>

Java腳本

  function getXY(e) {
        var txtX = document.getElementById("xVal");
        var txtY = document.getElementById("yVal");

        MouseX = (e).offsetX;
        MouseY = (e).offsetY;

        txtX.value = MouseX;
        txtY.value = MouseY;
    }

$(document.getElementById('#Image')).click(function() {

        launchWindow('#submitDialog');

        $(window).resize(function() {

            var box = $('#container .window');

            //Get the screen height and width
            var maskHeight = $(document).height();
            var maskWidth = $(document).width();

            //Set height and width to mask to fill up the whole screen
            $('#mask').css({ 'width': maskWidth, 'height': maskHeight });

            //Get the window height and width

        //transition effect     
        $('#mask').fadeIn(500);
        $('#mask').fadeTo("fast", 0.8);

        //Set the popup window to center

        $(id).css('left', winW / 2 - winW / 2);

        //These are not setting the label text :(
        $('#lblX').text($('#xVal').val());
        $('#lblY').text($('#yVal').val());

的CSS

#mask

下面的解決方案解決了我之前遇到的所有問題。 我使模態表單“居中”的解決方法有些破綻，但非常適合我的目的。 希望這對外面的人有用！

的HTML

<a id="imageAnchor" onmouseover="document.body.style.cursor='crossHair'"
    onmouseout="document.body.style.cursor='default'" onmousemove="getXY(event)">
       <img id="Image" src="../Images/TestImage.jpg" alt=""/></a><br/><br/>

X = <input type="text" id="xVal" size="2" readonly="true"/> &nbsp;
Y = <input type="text" id="yVal" size="2" readonly="true"/><br/><br/>

<div id="mask"></div>
<div id="container">
<div id="submitDialog" class="window">

X-coordinate:<asp:Label ID="lblX" runat="server"></asp:Label><br/>
Y-coordinate:<asp:Label ID="lblY" runat="server"></asp:Label><br/>

<asp:HiddenField id="xCo" runat="server"/>
<asp:HiddenField id="yCo" runat="server"/>

Answer 2

$(document.getElementById('#Image')).click(function(e) {

    // Add the event argument to the handler function to get mouse position
    // then pass that into the launch window function.

    //Put in the DIV id you want to display
    launchWindow('#submitDialog',e);

    $(window).resize(function() {
        var box = $('#container .window');

        //Get the screen height and width
        var maskHeight = $(document).height();
        var maskWidth = $(document).width();

        //Set height and width to mask to fill up the whole screen
        $('#mask').css({ 'width': maskWidth + 'px', 'height': maskHeight + 'px' });

        //Get the window height and width
        var winH = $(document).height();
        var winW = $(document).width();

        //Set the popup window to center
        // You need the height of your popup to do this.

        var pHeight = $(id).height();
        var pWidth = $(id).width();

        // Check to see if the window will come off the page, because
        // you're not gonna want that.

        var top = ((winH - pHeight) > 0) ? (winH - pHeight) / 2 : 0;
        var left =  ((winW - pWidth) > 0) ? (winW - pWidth) / 2 : 0;

        // If you don't set it to 'px' you may have trouble with some browsers

        box.css('top', top + 'px');
        box.css('left', left + 'px');
    });
});
function launchWindow(id,mouse) {

    var offset = $('#Image').offset();

    // Here are the coordinates you were looking for

    var coords = {
       x: mouse.pageX - offset.left;
       y: mouse.pageY - offset.top;
    }
    //Get the screen height and width
    var maskHeight = $(document).height();
    var maskWidth = $(document).width();

    //Get the window height and width
    var winH = $(document).height();
    var winW = $(document).width();

    //Set heigth and width to mask to fill up the whole screen 
    //and mask position
    $('#mask').css({ 'width': maskWidth, 'height': maskHeight });
    $('#mask').css({ 'top': 0, 'left': 0});

    //transition effect     
    $('#mask').fadeIn(500);
    $('#mask').fadeTo("fast", 0.8);

    //Set the popup window to center
    // You need the height of your popup to do this.

    var pHeight = $(id).height();
    var pWidth = $(id).width();

    // Check to see if the window will come off the page, because
    // you're not gonna want that.

    var top = ((winH - pHeight) > 0) ? (winH - pHeight) / 2 : 0;
    var left =  ((winW - pWidth) > 0) ? (winW - pWidth) / 2 : 0;

    $(id).css('top', top + 'px');
    $(id).css('left', left + 'px');

    //transition effect
    $(id).fadeIn(500);

    //These are not setting the label text :(
    $('#lblX').text(coords.x);
    $('#lblY').text(coords.y);
