我有一个 HTML 表单,其中有两个带有选项的选择元素和两个输入元素。
<form>
<select name="highSchool">
<option value="8342">Clinton High School</option>
<option value="9576">Washington High School</option>
<option value="8172">Roosevelt High School</option>
<option value="5431">Lincoln High School</option>
<option value="2460">Kennedy High School</option>
</select>
<br><br>
<select name="title">
<option value="1">Amazing Artist</option>
<option value="2">Awesome Athlete</option>
<option value="3">Marvelous Musician</option>
<option value="4">Scholar Student</option>
<option value="5">Wonderful Writer</option>
</select>
<br><br>
<input type="text" name='firstName' size="80" maxlength='30'>
<br><br>
<input type="text" name='lastName' size="80" maxlength='30'>
<br><br>
<button onclick="myFunction1()">Submit</button>
</form>
我有一个脚本可以根据随机字典自动填充字段并提交表单:<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
var random_dict = {'highSchool': 'Washington High School',
'title': 'Marvelous Musician',
'firstName': 'John',
'lastName':'Smith'}
//find correct option and select it
$("select[name='highSchool']").find('option').each(function(index,element){
if (element.text === random_dict.highSchool){
$("select[name ='highSchool']").val(element.value);
};
});
//find correct option and select it
$("select[name='title']").find('option').each(function(index,element){
if (element.text === random_dict.title){
$("select[name ='title']").val(element.value);
};
});
//fill the input elements
$("input[name ='firstName']").val(random_dict.firstName);
$("input[name ='lastName']").val(random_dict.lastName);
//submit form when done, this is the second form on the page
document.forms[1].submit();
}
</script>
我只能将选择选项作为 element.text
接收,所以我遍历选择选项,直到找到相应的 element.value
。这个脚本在我运行时有效。我想在新窗口中打开我的表单并执行所有相同的操作。我试图像这样重新编写它,但它不起作用:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
var windowName = $(this).attr('id');
var newWindow = window.open('http://www.exampleweb/example.phtml', windowName, "height=300,width=400");
var random_dict = {'highSchool': 'Washington High School',
'title': 'Marvelous Musician',
'firstName': 'John',
'lastName':'Smith'}
newWindow.document.$("select[name='highSchool']").find('option').each(function(index,element){ if (element.text === random_dict.highSchool){
newWindow.document.$("select[name ='highSchool']").val(element.value);
};
});
newWindow.document.$("select[name='title']").find('option').each(function(index,element){ if (element.text === random_dict.title){
newWindow.document.$("select[name ='title']").val(element.value);
};
});
newWindow.document.$("input[name ='firstName']").val(random_dict.firstName);
newWindow.document.$("input[name ='lastName']").val(random_dict.lastName);
newWindow.document.forms[1].submit();
}
</script>
如何调整所有 jQuery 选择器(如 $("input[name ='firstName']")
和 $("select[name='title']")
)以获取新窗口中的元素?我对 jQuery 和 Vanilla JS 解决方案持开放态度。
最佳答案
我相信您需要将脚本附加到新窗口,如下所示:
var newWindow = window.open('http://www.exampleweb/example.phtml', windowName, "height=300,width=400");
newWindow.document.createElement('script');
script.src = 'js/myScript.js';
newWindow.document.head.appendChild(script);
要访问新窗口中的元素,您只需引用 newWindow 的文档,如下所示:var newWindow = window.open('http://www.exampleweb/example.phtml', windowName, "height=300,width=400");
newWindow.document.$("input[name ='firstName']").html('test');
将脚本部分翻译为 Vanilla JS 以对 newWindow 执行完全相同的操作:var windowName = $(this).attr('id');
var newWindow = window.open('http://www.exampleweb/example.phtml', windowName, "height=300,width=400");
$(newWindow).on("load", function()
{
for (var i = 0; i < newWindow.document.querySelector("select[name='highSchool']").options.length; i++){
var option = newWindow.document.querySelector("select[name='highSchool']").options[i];
if (option.text === random_dict.highSchool){
newWindow.document.querySelector("select[name='highSchool']").value = option.value;
break;
};
};
for (var j = 0; j < newWindow.document.querySelector("select[name='title']").options.length; j++){
var option1 = newWindow.document.querySelector("select[name='title']").options[j];
if (option1.text === random_dict.title){
newWindow.document.querySelector("select[name='title']").value = option1.value;
break;
};
};
newWindow.document.querySelector("input[name='firstName']").value = random_dict.firstName;
newWindow.document.querySelector("input[name='lastName']").value = random_dict.lastName;
});
