在formstack表单中,我需要能够将列表作为参数传递给表单,并从该列表中创建用户可以选择并保存在formstack数据库中的复选框或下拉菜单并发送到所有其他领域的集成。以下是我要发送内容的示例:
http://theformurl?list=option1,option2,option3,option4
由此,我试图在头部,页脚或嵌入的代码中使用代码插入,以在负载上创建一个看起来像所有其他字段一样的新字段。
我一直在修改Jenna Molby的方法,用这里的url参数动态修改html:

但到目前为止还没有运气。目前,我还没有成功地将动态文本填充到表单中,更不用说一个表单字段然后与formstack的后端进行对话。
这是否可行,如果是这样,任何人都可以推荐一种方法或线程来解决这个问题吗?

感谢Eric的建议,我能够到达那里一半。页脚中的此代码可以包含您已通过id在表单中插入的复选框。它将使用您在网址中发送的值替换该复选框。但是当你提交时,Formstack不会抓住这些选择。
<script>
document.addEventListener("DOMContentLoaded", function(event) {
var url = new URL(window.location.href);
//Put field number in var fieldNumber
var fieldNumber = "12345678";
//Put the parameter you're searching for in var param
var param = "parameter name";
//if you want a prefix before your values in the checkbox, use prefix
var prefix = "Prefix ";
//Put the question you want to ask here.
var theQuestion = "Which of the values that came through the url will you select?";
//What should the single checkbox say if no parameters are passed?
var theDefaultBox = "No variables were contained in the parameter.";
var theField = "field" + fieldNumber;
var theFieldID = "fsCell"+fieldNumber;
var values = url.searchParams.get(param).split(",");
var theFieldHTMLfront = "";
if (values) {theFieldHTMLfront = "<fieldset id=\"label"+fieldNumber+"\"><legend class=\"fsLabel fsLabelVertical\"><span>"+theQuestion+"</span></legend><div class=\"fieldset-content\"><label class=\"fsOptionLabel vertical\" for=\""+theField+"_1\"><input type=\"checkbox\" id=\""+theField+"_1\" name=\""+theField+"[]\" value=\""+ prefix + values[0] + "\" class=\"fsField vertical\" />"+ prefix + values[0] + "</label>";} else {theFieldHTMLfront = "<fieldset id=\"label"+fieldNumber+"\"><legend class=\"fsLabel fsLabelVertical\"><span>Which values may have observed or have knowledge about this event?</span></legend><div class=\"fieldset-content\"><label class=\"fsOptionLabel vertical\" for=\""+theField+"_1\"><input type=\"checkbox\" id=\""+theField+"_1\" name=\""+theField+"[]\" value=\""+theDefaultBox+"\" class=\"fsField vertical\" />test</label>";}
var theFieldHTMLback = "</div></fieldset>";
for (var i = 1; i < values.length; i++) {
theFieldHTMLfront += "<label class=\"fsOptionLabel vertical\" for=\""+theField+(i+1)+"\"><input type=\"checkbox\" id=\""+theField+(i+1)+"\" name=\""+theField+"[]\" value=\""+prefix+values[i]+"\" class=\"fsField vertical\" />"+ prefix + values[i] + "</label>";
}
var theFieldHTML = theFieldHTMLfront + theFieldHTMLback;
document.getElementById(theFieldID).innerHTML = theFieldHTML;
});
</script>
关于如何在提交时与Formstack交谈的任何想法?
答案 0 :(得分:0)
不熟悉formstack或者你从URL获得了什么,放入表格或什么类型,但我会在黑暗中拍摄。
也许是这样的:
var paramsToGet = ['param', 'param', 'param'];
document.addEventListener("DOMContentLoaded", function(event) {
let url = new URL(window.location.href);
paramsToGet.forEach((v)=>{
let thisParam = url.searchParams.get(param);
newFormElement(thisParam, x, x, "Default Value");
})
});
var newFormElement = (type, element_id, target_id, default_value) => {
default_value = default_value || null;
let el = document.createElement(type);
el.id = element_id;
if (default_value) {el.value = default_value;}
document.getElementById(target_id).appendChild(el);
}

所以我设法找到适合我的解决方案。谢谢Eric让我开始。
它需要在要使用它的表单中添加两个字段:(1)将写入所选值的隐藏文本输入字段,以及(2)此代码将覆盖的占位符复选框字段。你需要获取他们的身份证号码,我通过打开实时表格和查看来源来做到这一点。
<script>
var selectedValues = [];
//This code goes in your Formstack theme footer. In the form that you want to add dynamic checkboxes to, create two fields using the WYSIWYG editor: a checkbox field and a text entry field. Make the text entry field hidden. You will need to know the id number of both the text entry and checkbox fields.
//Put the text entry field number in var textFieldNumber
var textFieldNumber = "field"+"12345678";
var index;
var checkboxFieldNumber = "12345679";
//Put the parameter you're searching for in var param
var param = "param";
//if you want a prefix before your values in the checkbox, use prefix
var prefix = "";
//Put the question you want to ask here.
var theQuestion = "Your question?";
//What should the single checkbox say if no parameters are passed?
var theDefaultBox = "Default message.";
document.addEventListener("DOMContentLoaded", function(event) {
var url = new URL(window.location.href);
//Put checkbox field number in var checkboxFieldNumber
//Build the replacement HTML for the placeholder checkbox field.
var theField = "field" + checkboxFieldNumber;
var theFieldID = "fsCell"+checkboxFieldNumber;
var values = url.searchParams.get(param).split(",") || null;
var theFieldHTMLfront = "";
if (values) {theFieldHTMLfront = "<fieldset id=\"label"+checkboxFieldNumber+"\"><legend class=\"fsLabel fsLabelVertical\"><span>"+theQuestion+"</span></legend><div class=\"fieldset-content\"><label class=\"fsOptionLabel vertical\" for=\""+theField+"_1\"><input type=\"checkbox\" id=\""+theField+"_1\" name=\""+theField+"[]\" value=\""+values[0]+"\" onchange=\"checkBoxToggle(this)\" class=\"fsField vertical\" />"+ prefix + values[0] + "</label>";} else {theFieldHTMLfront = "<fieldset id=\"label"+checkboxFieldNumber+"\"><legend class=\"fsLabel fsLabelVertical\"><span>Which values may have observed or have knowledge about this event?</span></legend><div class=\"fieldset-content\"><label class=\"fsOptionLabel vertical\" for=\""+theField+"_1\"><input type=\"checkbox\" id=\""+theField+"_1\" name=\""+theField+"[]\" value=\""+theDefaultBox+"\" onchange=\"checkBoxToggle(this)\" class=\"fsField vertical\" />test</label>";}
var theFieldHTMLback = "</div></fieldset>";
//iterate through the array found in the url parameters, adding a new checkbox option for each element in the array.
if (values) {for (var i = 1; i < values.length; i++) {
theFieldHTMLfront += "<label class=\"fsOptionLabel vertical\" for=\""+theField+(i+1)+"\"><input type=\"checkbox\" id=\""+theField+"_"+(i+1)+"\" name=\""+theField+"[]\" value=\""+values[i]+"\" onchange=\"checkBoxToggle(this)\" class=\"fsField vertical\" />"+ prefix + values[i] + "</label>";
};}
//finalize replacement HTML
var theFieldHTML = theFieldHTMLfront + theFieldHTMLback;
//write new HTML to DOM
document.getElementById(theFieldID).innerHTML = theFieldHTML;
});
function checkBoxToggle(thisBox) {
if(thisBox.checked) {
//When a new checkbox is selected, add its value to array selectedValues, sort it, and write it to the text entry field.
selectedValues.push(thisBox.value);
selectedValues.sort();
document.getElementById(textFieldNumber).value = selectedValues;
} else {
//When a checkbox is deselected, splice its value out of array selectedValues and write the array to the text entry field's value
index = selectedValues.indexOf(thisBox.value);
if (index > -1) {
selectedValues.splice(index, 1);
document.getElementById(textFieldNumber).value = selectedValues;
}
}
}
