使用带有javascript变量的popupWindow = window.open

Question

我有以下脚本:

<script type="text/javascript">
        function train(roww){
        $.post ('getpeopleinjobs.php',{ 
        postvarposition: form["position"+roww].value,
        postvarjob: form["job"+roww].value,
        postvarperson: form["person"+roww].value, 
        postrow: roww},
            function(output){ 
                popupWindow = window.open('trainingneeded.php?position=postvarposition&amp;job=postvarjob&amp;person=postvarperson','popUpWindow','height=400,width=1000,left=10,top=10,resizable=yes,scrollbars=yes,toolbar=no,menubar=no,location=no,directories=no,status=yes')
                    });
                }
</script>

我测试了脚本,它100%工作.我的问题是我的变量,postvarposition,postvarjob和postvarperson作为文本传递到URL字符串而不是实际变量.

如何格式化线条

popupWindow = window.open('trainingneeded.php?position=postvarposition&job=postvarjob&person=postvarperson','popUpWindow','height=400,width=1000,left=10,top=10,resizable=yes,scrollbars=yes,toolbar=no,menubar=no,location=no,directories=no,status=yes')

这样变量就作为变量而不是文本传递.

提前致谢.

您需要将变量连接到字符串中:

'trainingneeded.php?position=' + postvarposition + '&job=' + postvarjob + '&person=' + postvarperson

编辑:

使用您的代码,您可以看到.post调用由3部分组成:url(getpeopleinjobs.php),要传递的参数(包含在{}中)和成功处理程序(函数).这些中的每一个都在范围上是分开的,因此它们都不能访问任何其他的.基本上,您的成功处理程序不知道"postvarposition"是什么.为了使其可见,您必须将变量置于其容器范围之外.在这种情况下,您必须从{}中删除这些项的分配,并将它们放在方法.post调用之外.

<script type="text/javascript">
    function train(roww){
    $.post ('getpeopleinjobs.php',{ 
    // Because this is inside a {} these variables
    // can be considered "trapped" inside this scope
    postvarposition: form["position"+roww].value,
    postvarjob: form["job"+roww].value,
    postvarperson: form["person"+roww].value, 
    postrow: roww},
        function(output){ 
            popupWindow = window.open('trainingneeded.php?position=postvarposition&amp;job=postvarjob&amp;person=postvarperson','popUpWindow','height=400,width=1000,left=10,top=10,resizable=yes,scrollbars=yes,toolbar=no,menubar=no,location=no,directories=no,status=yes')
                });
            }
</script>

一个可能的解决方案是:

<script type="text/javascript">
    function train(roww){

        // declare them and assign them out here
        var position = form["position"+roww].value;
        var job = form["job"+roww].value;
        var person = form["person"+roww].value;

        $.post ('getpeopleinjobs.php',{ 
            postvarposition: position,
            postvarjob: job,
            postvarperson: person, 
            postrow: roww },
        function(output){ 
            popupWindow = window.open('trainingneeded.php?position=' + position + '&amp;job=' + job + '&amp;person=' + person,'popUpWindow','height=400,width=1000,left=10,top=10,resizable=yes,scrollbars=yes,toolbar=no,menubar=no,location=no,directories=no,status=yes');
                });
            }
</script>
